FIELD

This application relates generally to intelligent automated assistants and, more specifically, to delivering content from user experiences.

BACKGROUND

Intelligent automated assistants (or digital assistants) can provide a beneficial interface between human users and electronic devices. Such assistants can allow users to interact with devices or systems using natural language in spoken and/or text forms. For example, a user can provide a speech input containing a user request to a digital assistant operating on an electronic device. The digital assistant can interpret the user's intent from the speech input and operationalize the user's intent into tasks. The tasks can then be performed by executing one or more services of the electronic device, and a relevant output responsive to the user request can be returned to the user.

During a user experience, such as a vacation or social gathering, a user device may generate large amounts of media and other information, such as pictures, videos, notes, messages, and the like. A digital assistant can be helpful to assist a user in retrieving media and information previously generated on the device. However, digital assistants can be ineffective in gathering all relevant media and information for a specific user experience, such as, for example, based on a broad request for content related to the user experience.

SUMMARY

Systems and processes for operating an intelligent automated assistant are provided. In one example process, a speech input is received from a user. In response to determining that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, one or more parameters referencing a user experience of the user are identified. Metadata associated with the referenced user experience is obtained from an experiential data structure. Based on the metadata, one or more media items associated with the referenced are retrieved based on the metadata. The one or more media items associated with the referenced user experience are output together.

DETAILED DESCRIPTION

In the following description of examples, reference is made to the accompanying drawings in which are shown by way of illustration specific examples that can be practiced. It is to be understood that other examples can be used and structural changes can be made without departing from the scope of the various examples.

Conventional techniques for retrieving content associated with a user experience are generally inefficient. In particular, media and other information associated with user experiences may be ineffectively organized, resulting in difficulty when attempting to re-create the experiences for the user. Furthermore, this difficultly is compounded given the vast amount of media and information that users typically create on a regular basis. Conventional techniques for responding to user requests for experience-related content are also ineffective, and at best, monotonous. For example, in response to a user input “What was the seafood restaurant we ate at last week,” conventional techniques would generally fail to understand the user's intent, much less provide an engaging response in addition to identifying the requested location.

In accordance with some systems, computer-readable media, and processes described herein, content delivery for user experiences is performed by a digital assistant in a more efficient, accurate, and content-rich manner. In one example process, a speech input is received from a user. The process determines whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In response to a determination that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, one or more parameters referencing a user experience of the user are identified from the speech input. Metadata associated with the referenced user experience is obtained from an experiential data structure. Based on the metadata associated with the referenced user experience, one or more media items associated with the referenced user experience are retrieved. As a result, the one or more media items associated with the referenced user experience are output together.

In another example process, a user interface is displayed including at least one application, the at least one application associated with one or more parameters. The process determines whether the one or more parameters are associated with at least one user experience. In response to determining that the one or more parameters are associated with at least one user experience, the process obtains, from an experiential data structure, metadata associated with the at least one user experience, and the process further displays an affordance associated with the at least one application. A user input is received, including a selection of the affordance associated with the at least one application. In response to receiving the user input, at least one media item is output based on the metadata associated with the at least one user experience.

Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first input could be termed a second input, and, similarly, a second input could be termed a first input, without departing from the scope of the various described examples. The first input and the second input are both inputs and, in some cases, are separate and different inputs.

The terminology used in the description of the various described examples herein is for the purpose of describing particular examples only and is not intended to be limiting. As used in the description of the various described examples and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

The term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

1. System and Environment

FIG. 1 illustrates a block diagram of system 100 according to various examples. In some examples, system 100 implements a digital assistant. The terms “digital assistant,” “virtual assistant,” “intelligent automated assistant,” or “automatic digital assistant” refer to any information processing system that interprets natural language input in spoken and/or textual form to infer user intent, and performs actions based on the inferred user intent. For example, to act on an inferred user intent, the system performs one or more of the following: identifying a task flow with steps and parameters designed to accomplish the inferred user intent, inputting specific requirements from the inferred user intent into the task flow; executing the task flow by invoking programs, methods, services, APIs, or the like; and generating output responses to the user in an audible (e.g., speech) and/or visual form.

Specifically, a digital assistant is capable of accepting a user request at least partially in the form of a natural language command, request, statement, narrative, and/or inquiry. Typically, the user request seeks either an informational answer or performance of a task by the digital assistant. A satisfactory response to the user request includes a provision of the requested informational answer, a performance of the requested task, or a combination of the two. For example, a user asks the digital assistant a question, such as “Where am I right now?” Based on the user's current location, the digital assistant answers, “You are in Central Park near the west gate.” The user also requests the performance of a task, for example, “Please invite my friends to my girlfriend's birthday party next week.” In response, the digital assistant can acknowledge the request by saying “Yes, right away,” and then send a suitable calendar invite on behalf of the user to each of the user's friends listed in the user's electronic address book. During performance of a requested task, the digital assistant sometimes interacts with the user in a continuous dialogue involving multiple exchanges of information over an extended period of time. There are numerous other ways of interacting with a digital assistant to request information or performance of various tasks. In addition to providing verbal responses and taking programmed actions, the digital assistant also provides responses in other visual or audio forms, e.g., as text, alerts, music, videos, animations, etc.

As shown in FIG. 1, in some examples, a digital assistant is implemented according to a client-server model. The digital assistant includes client-side portion 102 (hereafter “DA client 102”) executed on user device 104 and server-side portion 106 (hereafter “DA server 106”) executed on server system 108. DA client 102 communicates with DA server 106 through one or more networks 110. DA client 102 provides client-side functionalities such as user-facing input and output processing and communication with DA server 106. DA server 106 provides server-side functionalities for any number of DA clients 102 each residing on a respective user device 104.

In some examples, DA server 106 includes client-facing I/O interface 112, one or more processing modules 114, data and models 116, and I/O interface to external services 118. The client-facing I/O interface 112 facilitates the client-facing input and output processing for DA server 106. One or more processing modules 114 utilize data and models 116 to process speech input and determine the user's intent based on natural language input. Further, one or more processing modules 114 perform task execution based on inferred user intent. In some examples, DA server 106 communicates with external services 120 through network(s) 110 for task completion or information acquisition. I/O interface to external services 118 facilitates such communications.

User device 104 can be any suitable electronic device. In some examples, user device 104 is a portable multifunctional device (e.g., device 200, described below with reference to FIG. 2A), a multifunctional device (e.g., device 400, described below with reference to FIG. 4), or a personal electronic device (e.g., device 600, described below with reference to FIG. 6A-B.) A portable multifunctional device is, for example, a mobile telephone that also contains other functions, such as PDA and/or music player functions. Specific examples of portable multifunction devices include the Apple Watch®, iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other examples of portable multifunction devices include, without limitation, earphones/headphones, speakers, and laptop or tablet computers. Further, in some examples, user device 104 is a non-portable multifunctional device. In particular, user device 104 is a desktop computer, a game console, a speaker, a television, or a television set-top box. In some examples, user device 104 includes a touch-sensitive surface (e.g., touch screen displays and/or touchpads). Further, user device 104 optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick. Various examples of electronic devices, such as multifunctional devices, are described below in greater detail.

Examples of communication network(s) 110 include local area networks (LAN) and wide area networks (WAN), e.g., the Internet. Communication network(s) 110 is implemented using any known network protocol, including various wired or wireless protocols, such as, for example, Ethernet, Universal Serial Bus (USB), FIREWIRE, Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wi-Fi, voice over Internet Protocol (VoIP), Wi-MAX, or any other suitable communication protocol.

Server system 108 is implemented on one or more standalone data processing apparatus or a distributed network of computers. In some examples, server system 108 also employs various virtual devices and/or services of third-party service providers (e.g., third-party cloud service providers) to provide the underlying computing resources and/or infrastructure resources of server system 108.

In some examples, user device 104 communicates with DA server 106 via second user device 122. Second user device 122 is similar or identical to user device 104. For example, second user device 122 is similar to devices 200, 400, or 600 described below with reference to FIGS. 2A, 4, and 6A-B. User device 104 is configured to communicatively couple to second user device 122 via a direct communication connection, such as Bluetooth, NFC, BTLE, or the like, or via a wired or wireless network, such as a local Wi-Fi network. In some examples, second user device 122 is configured to act as a proxy between user device 104 and DA server 106. For example, DA client 102 of user device 104 is configured to transmit information (e.g., a user request received at user device 104) to DA server 106 via second user device 122. DA server 106 processes the information and returns relevant data (e.g., data content responsive to the user request) to user device 104 via second user device 122.

In some examples, user device 104 is configured to communicate abbreviated requests for data to second user device 122 to reduce the amount of information transmitted from user device 104. Second user device 122 is configured to determine supplemental information to add to the abbreviated request to generate a complete request to transmit to DA server 106. This system architecture can advantageously allow user device 104 having limited communication capabilities and/or limited battery power (e.g., a watch or a similar compact electronic device) to access services provided by DA server 106 by using second user device 122, having greater communication capabilities and/or battery power (e.g., a mobile phone, laptop computer, tablet computer, or the like), as a proxy to DA server 106. While only two user devices 104 and 122 are shown in FIG. 1, it should be appreciated that system 100, in some examples, includes any number and type of user devices configured in this proxy configuration to communicate with DA server system 106.

Although the digital assistant shown in FIG. 1 includes both a client-side portion (e.g., DA client 102) and a server-side portion (e.g., DA server 106), in some examples, the functions of a digital assistant are implemented as a standalone application installed on a user device. In addition, the divisions of functionalities between the client and server portions of the digital assistant can vary in different implementations. For instance, in some examples, the DA client is a thin-client that provides only user-facing input and output processing functions, and delegates all other functionalities of the digital assistant to a backend server.

2. Electronic Devices

Attention is now directed toward embodiments of electronic devices for implementing the client-side portion of a digital assistant. FIG. 2A is a block diagram illustrating portable multifunction device 200 with touch-sensitive display system 212 in accordance with some embodiments. Touch-sensitive display 212 is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device 200 includes memory 202 (which optionally includes one or more computer-readable storage mediums), memory controller 222, one or more processing units (CPUs) 220, peripherals interface 218, RF circuitry 208, audio circuitry 210, speaker 211, microphone 213, input/output (I/O) subsystem 206, other input control devices 216, and external port 224. Device 200 optionally includes one or more optical sensors 264. Device 200 optionally includes one or more contact intensity sensors 265 for detecting intensity of contacts on device 200 (e.g., a touch-sensitive surface such as touch-sensitive display system 212 of device 200). Device 200 optionally includes one or more tactile output generators 267 for generating tactile outputs on device 200 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 212 of device 200 or touchpad 455 of device 400). These components optionally communicate over one or more communication buses or signal lines 203.

As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button).

As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that device 200 is only one example of a portable multifunction device, and that device 200 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 2A are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits.

Memory 202 includes one or more computer-readable storage mediums. The computer-readable storage mediums are, for example, tangible and non-transitory. Memory 202 includes high-speed random access memory and also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller 222 controls access to memory 202 by other components of device 200.

In some examples, a non-transitory computer-readable storage medium of memory 202 is used to store instructions (e.g., for performing aspects of processes described below) for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. In other examples, the instructions (e.g., for performing aspects of the processes described below) are stored on a non-transitory computer-readable storage medium (not shown) of the server system 108 or are divided between the non-transitory computer-readable storage medium of memory 202 and the non-transitory computer-readable storage medium of server system 108.

Peripherals interface 218 is used to couple input and output peripherals of the device to CPU 220 and memory 202. The one or more processors 220 run or execute various software programs and/or sets of instructions stored in memory 202 to perform various functions for device 200 and to process data. In some embodiments, peripherals interface 218, CPU 220, and memory controller 222 are implemented on a single chip, such as chip 204. In some other embodiments, they are implemented on separate chips.

RF (radio frequency) circuitry 208 receives and sends RF signals, also called electromagnetic signals. RF circuitry 208 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry 208 optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 208 optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The RF circuitry 208 optionally includes well-known circuitry for detecting near field communication (NFC) fields, such as by a short-range communication radio. The wireless communication optionally uses any of a plurality of communications standards, protocols, and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Bluetooth Low Energy (BTLE), Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and/or IEEE 802.11ac), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

Audio circuitry 210, speaker 211, and microphone 213 provide an audio interface between a user and device 200. Audio circuitry 210 receives audio data from peripherals interface 218, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 211. Speaker 211 converts the electrical signal to human-audible sound waves. Audio circuitry 210 also receives electrical signals converted by microphone 213 from sound waves. Audio circuitry 210 converts the electrical signal to audio data and transmits the audio data to peripherals interface 218 for processing. Audio data are retrieved from and/or transmitted to memory 202 and/or RF circuitry 208 by peripherals interface 218. In some embodiments, audio circuitry 210 also includes a headset jack (e.g., 312, FIG. 3). The headset jack provides an interface between audio circuitry 210 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 206 couples input/output peripherals on device 200, such as touch screen 212 and other input control devices 216, to peripherals interface 218. I/O subsystem 206 optionally includes display controller 256, optical sensor controller 258, intensity sensor controller 259, haptic feedback controller 261, and one or more input controllers 260 for other input or control devices. The one or more input controllers 260 receive/send electrical signals from/to other input control devices 216. The other input control devices 216 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 260 are, optionally, coupled to any (or none) of the following: a keyboard, an infrared port, a USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 308, FIG. 3) optionally include an up/down button for volume control of speaker 211 and/or microphone 213. The one or more buttons optionally include a push button (e.g., 306, FIG. 3).

A quick press of the push button disengages a lock of touch screen 212 or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g., 306) turns power to device 200 on or off. The user is able to customize a functionality of one or more of the buttons. Touch screen 212 is used to implement virtual or soft buttons and one or more soft keyboards.

Touch-sensitive display 212 provides an input interface and an output interface between the device and a user. Display controller 256 receives and/or sends electrical signals from/to touch screen 212. Touch screen 212 displays visual output to the user. The visual output includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output correspond to user-interface objects.

Touch screen 212 has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 212 and display controller 256 (along with any associated modules and/or sets of instructions in memory 202) detect contact (and any movement or breaking of the contact) on touch screen 212 and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen 212. In an exemplary embodiment, a point of contact between touch screen 212 and the user corresponds to a finger of the user.

Touch screen 212 uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 212 and display controller 256 detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 212. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif.

A touch-sensitive display in some embodiments of touch screen 212 is analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen 212 displays visual output from device 200, whereas touch-sensitive touchpads do not provide visual output.

A touch-sensitive display in some embodiments of touch screen 212 is as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser.

No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.

Touch screen 212 has, for example, a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user makes contact with touch screen 212 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 200 includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is a touch-sensitive surface that is separate from touch screen 212 or an extension of the touch-sensitive surface formed by the touch screen.

Device 200 also includes power system 262 for powering the various components. Power system 262 includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 200 also includes one or more optical sensors 264. FIG. 2A shows an optical sensor coupled to optical sensor controller 258 in I/O subsystem 206. Optical sensor 264 includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 264 receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module 243 (also called a camera module), optical sensor 264 captures still images or video. In some embodiments, an optical sensor is located on the back of device 200, opposite touch screen display 212 on the front of the device so that the touch screen display is used as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image is obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor 264 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 264 is used along with the touch screen display for both video conferencing and still and/or video image acquisition.

Device 200 optionally also includes one or more contact intensity sensors 265. FIG. 2A shows a contact intensity sensor coupled to intensity sensor controller 259 in I/O subsystem 206. Contact intensity sensor 265 optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor 265 receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 212). In some embodiments, at least one contact intensity sensor is located on the back of device 200, opposite touch screen display 212, which is located on the front of device 200.

Device 200 also includes one or more proximity sensors 266. FIG. 2A shows proximity sensor 266 coupled to peripherals interface 218. Alternately, proximity sensor 266 is coupled to input controller 260 in I/O subsystem 206. Proximity sensor 266 is performed as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen 212 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 200 optionally also includes one or more tactile output generators 267. FIG. 2A shows a tactile output generator coupled to haptic feedback controller 261 in I/O subsystem 206. Tactile output generator 267 optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor 265 receives tactile feedback generation instructions from haptic feedback module 233 and generates tactile outputs on device 200 that are capable of being sensed by a user of device 200. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 212) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 200) or laterally (e.g., back and forth in the same plane as a surface of device 200). In some embodiments, at least one tactile output generator sensor is located on the back of device 200, opposite touch screen display 212, which is located on the front of device 200.

Device 200 also includes one or more accelerometers 268. FIG. 2A shows accelerometer 268 coupled to peripherals interface 218. Alternately, accelerometer 268 is coupled to an input controller 260 in I/O subsystem 206. Accelerometer 268 performs, for example, as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 200 optionally includes, in addition to accelerometer(s) 268, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 200.

In some embodiments, the software components stored in memory 202 include operating system 226, communication module (or set of instructions) 228, contact/motion module (or set of instructions) 230, graphics module (or set of instructions) 232, text input module (or set of instructions) 234, Global Positioning System (GPS) module (or set of instructions) 235, Digital Assistant Client Module 229, and applications (or sets of instructions) 236. Further, memory 202 stores data and models, such as user data and models 231. Furthermore, in some embodiments, memory 202 (FIG. 2A) or 470 (FIG. 4) stores device/global internal state 257, as shown in FIGS. 2A and 4. Device/global internal state 257 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 212; sensor state, including information obtained from the device's various sensors and input control devices 216; and location information concerning the device's location and/or attitude.

Operating system 226 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 228 facilitates communication with other devices over one or more external ports 224 and also includes various software components for handling data received by RF circuitry 208 and/or external port 224. External port 224 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices.

Contact/motion module 230 optionally detects contact with touch screen 212 (in conjunction with display controller 256) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 230 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 230 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 230 and display controller 256 detect contact on a touchpad.

In some embodiments, contact/motion module 230 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 200). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

Contact/motion module 230 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event.

Graphics module 232 includes various known software components for rendering and displaying graphics on touch screen 212 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like.

In some embodiments, graphics module 232 stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module 232 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 256.

Haptic feedback module 233 includes various software components for generating instructions used by tactile output generator(s) 267 to produce tactile outputs at one or more locations on device 200 in response to user interactions with device 200.

Text input module 234, which is, in some examples, a component of graphics module 232, provides soft keyboards for entering text in various applications (e.g., contacts 237, email 240, IM 241, browser 247, and any other application that needs text input).

GPS module 235 determines the location of the device and provides this information for use in various applications (e.g., to telephone 238 for use in location-based dialing; to camera 243 as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Digital assistant client module 229 includes various client-side digital assistant instructions to provide the client-side functionalities of the digital assistant. For example, digital assistant client module 229 is capable of accepting voice input (e.g., speech input), text input, touch input, and/or gestural input through various user interfaces (e.g., microphone 213, accelerometer(s) 268, touch-sensitive display system 212, optical sensor(s) 229, other input control devices 216, etc.) of portable multifunction device 200. Digital assistant client module 229 is also capable of providing output in audio (e.g., speech output), visual, and/or tactile forms through various output interfaces (e.g., speaker 211, touch-sensitive display system 212, tactile output generator(s) 267, etc.) of portable multifunction device 200. For example, output is provided as voice, sound, alerts, text messages, menus, graphics, videos, animations, vibrations, and/or combinations of two or more of the above. During operation, digital assistant client module 229 communicates with DA server 106 using RF circuitry 208.

User data and models 231 include various data associated with the user (e.g., user-specific vocabulary data, user preference data, user-specified name pronunciations, data from the user's electronic address book, to-do lists, shopping lists, etc.) to provide the client-side functionalities of the digital assistant. Further, user data and models 231 include various models (e.g., speech recognition models, statistical language models, natural language processing models, ontology, task flow models, service models, etc.) for processing user input and determining user intent.

In some examples, digital assistant client module 229 utilizes the various sensors, subsystems, and peripheral devices of portable multifunction device 200 to gather additional information from the surrounding environment of the portable multifunction device 200 to establish a context associated with a user, the current user interaction, and/or the current user input. In some examples, digital assistant client module 229 provides the contextual information or a subset thereof with the user input to DA server 106 to help infer the user's intent. In some examples, the digital assistant also uses the contextual information to determine how to prepare and deliver outputs to the user. Contextual information is referred to as context data.

In some examples, the contextual information that accompanies the user input includes sensor information, e.g., lighting, ambient noise, ambient temperature, images or videos of the surrounding environment, etc. In some examples, the contextual information can also include the physical state of the device, e.g., device orientation, device location, device temperature, power level, speed, acceleration, motion patterns, cellular signals strength, etc. In some examples, information related to the software state of DA server 106, e.g., running processes, installed programs, past and present network activities, background services, error logs, resources usage, etc., and of portable multifunction device 200 is provided to DA server 106 as contextual information associated with a user input.

In some examples, the digital assistant client module 229 selectively provides information (e.g., user data 231) stored on the portable multifunction device 200 in response to requests from DA server 106. In some examples, digital assistant client module 229 also elicits additional input from the user via a natural language dialogue or other user interfaces upon request by DA server 106. Digital assistant client module 229 passes the additional input to DA server 106 to help DA server 106 in intent deduction and/or fulfillment of the user's intent expressed in the user request.

These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules can be combined or otherwise rearranged in various embodiments. For example, video player module can be combined with music player module into a single module (e.g., video and music player module 252, FIG. 2A). In some embodiments, memory 202 stores a subset of the modules and data structures identified above. Furthermore, memory 202 stores additional modules and data structures not described above.

In some embodiments, device 200 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 200, the number of physical input control devices (such as push buttons, dials, and the like) on device 200 is reduced.

The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 200 to a main, home, or root menu from any user interface that is displayed on device 200. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

FIG. 2B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 202 (FIG. 2A) or 470 (FIG. 4) includes event sorter 270 (e.g., in operating system 226) and a respective application 236-1 (e.g., any of the aforementioned applications 237-251, 255, 480-490).

Event sorter 270 receives event information and determines the application 236-1 and application view 291 of application 236-1 to which to deliver the event information. Event sorter 270 includes event monitor 271 and event dispatcher module 274. In some embodiments, application 236-1 includes application internal state 292, which indicates the current application view(s) displayed on touch-sensitive display 212 when the application is active or executing. In some embodiments, device/global internal state 257 is used by event sorter 270 to determine which application(s) is (are) currently active, and application internal state 292 is used by event sorter 270 to determine application views 291 to which to deliver event information.

In some embodiments, application internal state 292 includes additional information, such as one or more of: resume information to be used when application 236-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 236-1, a state queue for enabling the user to go back to a prior state or view of application 236-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 271 receives event information from peripherals interface 218. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 212, as part of a multi-touch gesture). Peripherals interface 218 transmits information it receives from I/O subsystem 206 or a sensor, such as proximity sensor 266, accelerometer(s) 268, and/or microphone 213 (through audio circuitry 210). Information that peripherals interface 218 receives from I/O subsystem 206 includes information from touch-sensitive display 212 or a touch-sensitive surface.

In some embodiments, event monitor 271 sends requests to the peripherals interface 218 at predetermined intervals. In response, peripherals interface 218 transmits event information. In other embodiments, peripherals interface 218 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 270 also includes a hit view determination module 272 and/or an active event recognizer determination module 273.

Hit view determination module 272 provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display 212 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is called the hit view, and the set of events that are recognized as proper inputs is determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 272 receives information related to sub events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 272 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module 272, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 273 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 273 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 273 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 274 dispatches the event information to an event recognizer (e.g., event recognizer 280). In embodiments including active event recognizer determination module 273, event dispatcher module 274 delivers the event information to an event recognizer determined by active event recognizer determination module 273. In some embodiments, event dispatcher module 274 stores in an event queue the event information, which is retrieved by a respective event receiver 282.

In some embodiments, operating system 226 includes event sorter 270. Alternatively, application 236-1 includes event sorter 270. In yet other embodiments, event sorter 270 is a stand-alone module, or a part of another module stored in memory 202, such as contact/motion module 230.

In some embodiments, application 236-1 includes a plurality of event handlers 290 and one or more application views 291, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 291 of the application 236-1 includes one or more event recognizers 280. Typically, a respective application view 291 includes a plurality of event recognizers 280. In other embodiments, one or more of event recognizers 280 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 236-1 inherits methods and other properties. In some embodiments, a respective event handler 290 includes one or more of: data updater 276, object updater 277, GUI updater 278, and/or event data 279 received from event sorter 270. Event handler 290 utilizes or calls data updater 276, object updater 277, or GUI updater 278 to update the application internal state 292. Alternatively, one or more of the application views 291 include one or more respective event handlers 290. Also, in some embodiments, one or more of data updater 276, object updater 277, and GUI updater 278 are included in a respective application view 291.

A respective event recognizer 280 receives event information (e.g., event data 279) from event sorter 270 and identifies an event from the event information. Event recognizer 280 includes event receiver 282 and event comparator 284. In some embodiments, event recognizer 280 also includes at least a subset of: metadata 283, and event delivery instructions 288 (which include sub-event delivery instructions).

Event receiver 282 receives event information from event sorter 270. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 284 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 284 includes event definitions 286. Event definitions 286 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (287-1), event 2 (287-2), and others. In some embodiments, sub-events in an event (287) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (287-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event 2 (287-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 212, and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 290.

In some embodiments, event definition 287 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 284 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 212, when a touch is detected on touch-sensitive display 212, event comparator 284 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 290, the event comparator uses the result of the hit test to determine which event handler 290 should be activated. For example, event comparator 284 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event (287) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 280 determines that the series of sub-events do not match any of the events in event definitions 286, the respective event recognizer 280 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 280 includes metadata 283 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 283 includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata 283 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 280 activates event handler 290 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 280 delivers event information associated with the event to event handler 290. Activating an event handler 290 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 280 throws a flag associated with the recognized event, and event handler 290 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 288 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 276 creates and updates data used in application 236-1. For example, data updater 276 updates the telephone number used in contacts module 237, or stores a video file used in video player module. In some embodiments, object updater 277 creates and updates objects used in application 236-1. For example, object updater 277 creates a new user-interface object or updates the position of a user-interface object. GUI updater 278 updates the GUI. For example, GUI updater 278 prepares display information and sends it to graphics module 232 for display on a touch-sensitive display.

In some embodiments, event handler(s) 290 includes or has access to data updater 276, object updater 277, and GUI updater 278. In some embodiments, data updater 276, object updater 277, and GUI updater 278 are included in a single module of a respective application 236-1 or application view 291. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 200 with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 3 illustrates a portable multifunction device 200 having a touch screen 212 in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 300. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 302 (not drawn to scale in the figure) or one or more styluses 303 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 200. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

Device 200 also includes one or more physical buttons, such as “home” or menu button 304. As described previously, menu button 304 is used to navigate to any application 236 in a set of applications that is executed on device 200. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 212.

In one embodiment, device 200 includes touch screen 212, menu button 304, push button 306 for powering the device on/off and locking the device, volume adjustment button(s) 308, subscriber identity module (SIM) card slot 310, headset jack 312, and docking/charging external port 224. Push button 306 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 200 also accepts verbal input for activation or deactivation of some functions through microphone 213. Device 200 also, optionally, includes one or more contact intensity sensors 265 for detecting intensity of contacts on touch screen 212 and/or one or more tactile output generators 267 for generating tactile outputs for a user of device 200.

FIG. 4 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 400 need not be portable. In some embodiments, device 400 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 400 typically includes one or more processing units (CPUs) 410, one or more network or other communications interfaces 460, memory 470, and one or more communication buses 420 for interconnecting these components. Communication buses 420 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 400 includes input/output (I/O) interface 430 comprising display 440, which is typically a touch screen display. I/O interface 430 also optionally includes a keyboard and/or mouse (or other pointing device) 450 and touchpad 455, tactile output generator 457 for generating tactile outputs on device 400 (e.g., similar to tactile output generator(s) 267 described above with reference to FIG. 2A), sensors 459 (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s) 265 described above with reference to FIG. 2A). Memory 470 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 470 optionally includes one or more storage devices remotely located from CPU(s) 410. In some embodiments, memory 470 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 202 of portable multifunction device 200 (FIG. 2A), or a subset thereof. Furthermore, memory 470 optionally stores additional programs, modules, and data structures not present in memory 202 of portable multifunction device 200. For example, memory 470 of device 400 optionally stores drawing module 480, presentation module 482, word processing module 484, website creation module 486, disk authoring module 488, and/or spreadsheet module 490, while memory 202 of portable multifunction device 200 (FIG. 2A) optionally does not store these modules.

Each of the above-identified elements in FIG. 4 is, in some examples, stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are combined or otherwise rearranged in various embodiments. In some embodiments, memory 470 stores a subset of the modules and data structures identified above. Furthermore, memory 470 stores additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces that can be implemented on, for example, portable multifunction device 200.

FIG. 5A illustrates an exemplary user interface for a menu of applications on portable multifunction device 200 in accordance with some embodiments. Similar user interfaces are implemented on device 400. In some embodiments, user interface 500 includes the following elements, or a subset or superset thereof:

Signal strength indicator(s) 502 for wireless communication(s), such as cellular and Wi-Fi signals;

-   -   Time 504;     -   Bluetooth indicator 505;     -   Battery status indicator 506;     -   Tray 508 with icons for frequently used applications, such as:         -   Icon 516 for telephone module 238, labeled “Phone,” which             optionally includes an indicator 514 of the number of missed             calls or voicemail messages;         -   Icon 518 for e-mail client module 240, labeled “Mail,” which             optionally includes an indicator 510 of the number of unread             e-mails;         -   Icon 520 for browser module 247, labeled “Browser;” and         -   Icon 522 for video and music player module 252, also             referred to as iPod (trademark of Apple Inc.) module 252,             labeled “iPod;” and     -   Icons for other applications, such as:         -   Icon 524 for IM module 241, labeled “Messages;”         -   Icon 526 for calendar module 248, labeled “Calendar;”         -   Icon 528 for image management module 244, labeled “Photos;”         -   Icon 530 for camera module 243, labeled “Camera;”         -   Icon 532 for online video module 255, labeled “Online             Video;”         -   Icon 534 for stocks widget 249-2, labeled “Stocks;”         -   Icon 536 for map module 254, labeled “Maps;”         -   Icon 538 for weather widget 249-1, labeled “Weather;”         -   Icon 540 for alarm clock widget 249-4, labeled “Clock;”         -   Icon 542 for workout support module 242, labeled “Workout             Support;”         -   Icon 544 for notes module 253, labeled “Notes;” and         -   Icon 546 for a settings application or module, labeled             “Settings,” which provides access to settings for device 200             and its various applications 236.

It should be noted that the icon labels illustrated in FIG. 5A are merely exemplary. For example, icon 522 for video and music player module 252 is optionally labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

FIG. 5B illustrates an exemplary user interface on a device (e.g., device 400, FIG. 4) with a touch-sensitive surface 551 (e.g., a tablet or touchpad 455, FIG. 4) that is separate from the display 550 (e.g., touch screen display 212). Device 400 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 457) for detecting intensity of contacts on touch-sensitive surface 551 and/or one or more tactile output generators 459 for generating tactile outputs for a user of device 400.

Although some of the examples which follow will be given with reference to inputs on touch screen display 212 (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 5B. In some embodiments, the touch-sensitive surface (e.g., 551 in FIG. 5B) has a primary axis (e.g., 552 in FIG. 5B) that corresponds to a primary axis (e.g., 553 in FIG. 5B) on the display (e.g., 550). In accordance with these embodiments, the device detects contacts (e.g., 560 and 562 in FIG. 5B) with the touch-sensitive surface 551 at locations that correspond to respective locations on the display (e.g., in FIG. 5B, 560 corresponds to 568 and 562 corresponds to 570). In this way, user inputs (e.g., contacts 560 and 562, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 551 in FIG. 5B) are used by the device to manipulate the user interface on the display (e.g., 550 in FIG. 5B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

FIG. 6A illustrates exemplary personal electronic device 600. Device 600 includes body 602. In some embodiments, device 600 includes some or all of the features described with respect to devices 200 and 400 (e.g., FIGS. 2A-4). In some embodiments, device 600 has touch-sensitive display screen 604, hereafter touch screen 604. Alternatively, or in addition to touch screen 604, device 600 has a display and a touch-sensitive surface. As with devices 200 and 400, in some embodiments, touch screen 604 (or the touch-sensitive surface) has one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen 604 (or the touch-sensitive surface) provide output data that represents the intensity of touches. The user interface of device 600 responds to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device 600.

Techniques for detecting and processing touch intensity are found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, each of which is hereby incorporated by reference in their entirety.

In some embodiments, device 600 has one or more input mechanisms 606 and 608. Input mechanisms 606 and 608, if included, are physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device 600 has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device 600 with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms permit device 600 to be worn by a user.

FIG. 6B depicts exemplary personal electronic device 600. In some embodiments, device 600 includes some or all of the components described with respect to FIGS. 2A, 2B, and 4. Device 600 has bus 612 that operatively couples I/O section 614 with one or more computer processors 616 and memory 618. I/O section 614 is connected to display 604, which can have touch-sensitive component 622 and, optionally, touch-intensity sensitive component 624. In addition, I/O section 614 is connected with communication unit 630 for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device 600 includes input mechanisms 606 and/or 608. Input mechanism 606 is a rotatable input device or a depressible and rotatable input device, for example. Input mechanism 608 is a button, in some examples.

Input mechanism 608 is a microphone, in some examples. Personal electronic device 600 includes, for example, various sensors, such as GPS sensor 632, accelerometer 634, directional sensor 640 (e.g., compass), gyroscope 636, motion sensor 638, and/or a combination thereof, all of which are operatively connected to I/O section 614.

Memory 618 of personal electronic device 600 is a non-transitory computer-readable storage medium, for storing computer-executable instructions, which, when executed by one or more computer processors 616, for example, cause the computer processors to perform the techniques and processes described below. The computer-executable instructions, for example, are also stored and/or transported within any non-transitory computer-readable storage medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. Personal electronic device 600 is not limited to the components and configuration of FIG. 6B, but can include other or additional components in multiple configurations.

As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, for example, displayed on the display screen of devices 200, 400, and/or 600 (FIGS. 2A, 4, and 6A-B). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) each constitutes an affordance.

As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 455 in FIG. 4 or touch-sensitive surface 551 in FIG. 5B) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system 212 in FIG. 2A or touch screen 212 in FIG. 5A) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds includes a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation.

In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface receives a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location is based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm is applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity.

The intensity of a contact on the touch-sensitive surface is characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero.

In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input).

In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold.

3. Digital Assistant System

FIG. 7A illustrates a block diagram of digital assistant system 700 in accordance with various examples. In some examples, digital assistant system 700 is implemented on a standalone computer system. In some examples, digital assistant system 700 is distributed across multiple computers. In some examples, some of the modules and functions of the digital assistant are divided into a server portion and a client portion, where the client portion resides on one or more user devices (e.g., devices 104, 122, 200, 400, or 600) and communicates with the server portion (e.g., server system 108) through one or more networks, e.g., as shown in FIG. 1. In some examples, digital assistant system 700 is an implementation of server system 108 (and/or DA server 106) shown in FIG. 1. It should be noted that digital assistant system 700 is only one example of a digital assistant system, and that digital assistant system 700 can have more or fewer components than shown, can combine two or more components, or can have a different configuration or arrangement of the components. The various components shown in FIG. 7A are implemented in hardware, software instructions for execution by one or more processors, firmware, including one or more signal processing and/or application specific integrated circuits, or a combination thereof.

Digital assistant system 700 includes memory 702, one or more processors 704, input/output (I/O) interface 706, and network communications interface 708. These components can communicate with one another over one or more communication buses or signal lines 710.

In some examples, memory 702 includes a non-transitory computer-readable medium, such as high-speed random access memory and/or a non-volatile computer-readable storage medium (e.g., one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices).

In some examples, I/O interface 706 couples input/output devices 716 of digital assistant system 700, such as displays, keyboards, touch screens, and microphones, to user interface module 722. I/O interface 706, in conjunction with user interface module 722, receives user inputs (e.g., voice input, keyboard inputs, touch inputs, etc.) and processes them accordingly. In some examples, e.g., when the digital assistant is implemented on a standalone user device, digital assistant system 700 includes any of the components and I/O communication interfaces described with respect to devices 200, 400, or 600 in FIGS. 2A, 4, 6A-B, respectively. In some examples, digital assistant system 700 represents the server portion of a digital assistant implementation, and can interact with the user through a client-side portion residing on a user device (e.g., devices 104, 200, 400, or 600).

In some examples, the network communications interface 708 includes wired communication port(s) 712 and/or wireless transmission and reception circuitry 714. The wired communication port(s) receives and send communication signals via one or more wired interfaces, e.g., Ethernet, Universal Serial Bus (USB), FIREWIRE, etc. The wireless circuitry 714 receives and sends RF signals and/or optical signals from/to communications networks and other communications devices. The wireless communications use any of a plurality of communications standards, protocols, and technologies, such as GSM, EDGE, CDMA, TDMA, Bluetooth, Wi-Fi, VoIP, Wi-MAX, or any other suitable communication protocol. Network communications interface 708 enables communication between digital assistant system 700 with networks, such as the Internet, an intranet, and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN), and/or a metropolitan area network (MAN), and other devices.

In some examples, memory 702, or the computer-readable storage media of memory 702, stores programs, modules, instructions, and data structures including all or a subset of: operating system 718, communications module 720, user interface module 722, one or more applications 724, and digital assistant module 726. In particular, memory 702, or the computer-readable storage media of memory 702, stores instructions for performing the processes described below. One or more processors 704 execute these programs, modules, and instructions, and reads/writes from/to the data structures.

Operating system 718 (e.g., Darwin, RTXC, LINUX, UNIX, iOS, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communications between various hardware, firmware, and software components.

Communications module 720 facilitates communications between digital assistant system 700 with other devices over network communications interface 708. For example, communications module 720 communicates with RF circuitry 208 of electronic devices such as devices 200, 400, and 600 shown in FIGS. 2A, 4, 6A-B, respectively. Communications module 720 also includes various components for handling data received by wireless circuitry 714 and/or wired communications port 712.

User interface module 722 receives commands and/or inputs from a user via I/O interface 706 (e.g., from a keyboard, touch screen, pointing device, controller, and/or microphone), and generate user interface objects on a display. User interface module 722 also prepares and delivers outputs (e.g., speech, sound, animation, text, icons, vibrations, haptic feedback, light, etc.) to the user via the I/O interface 706 (e.g., through displays, audio channels, speakers, touch-pads, etc.).

Applications 724 include programs and/or modules that are configured to be executed by one or more processors 704. For example, if the digital assistant system is implemented on a standalone user device, applications 724 include user applications, such as games, a calendar application, a navigation application, or an email application. If digital assistant system 700 is implemented on a server, applications 724 include resource management applications, diagnostic applications, or scheduling applications, for example.

Memory 702 also stores digital assistant module 726 (or the server portion of a digital assistant). In some examples, digital assistant module 726 includes the following sub-modules, or a subset or superset thereof: input/output processing module 728, speech-to-text (STT) processing module 730, natural language processing module 732, dialogue flow processing module 734, task flow processing module 736, service processing module 738, and speech synthesis processing module 740. Each of these modules has access to one or more of the following systems or data and models of the digital assistant module 726, or a subset or superset thereof: ontology 760, vocabulary index 744, user data 748, task flow models 754, service models 756, and ASR systems 758.

In some examples, using the processing modules, data, and models implemented in digital assistant module 726, the digital assistant can perform at least some of the following: converting speech input into text; identifying a user's intent expressed in a natural language input received from the user; actively eliciting and obtaining information needed to fully infer the user's intent (e.g., by disambiguating words, games, intentions, etc.); determining the task flow for fulfilling the inferred intent; and executing the task flow to fulfill the inferred intent.

In some examples, as shown in FIG. 7B, I/O processing module 728 interacts with the user through I/O devices 716 in FIG. 7A or with a user device (e.g., devices 104, 200, 400, or 600) through network communications interface 708 in FIG. 7A to obtain user input (e.g., a speech input) and to provide responses (e.g., as speech outputs) to the user input. I/O processing module 728 optionally obtains contextual information associated with the user input from the user device, along with or shortly after the receipt of the user input. The contextual information includes user-specific data, vocabulary, and/or preferences relevant to the user input. In some examples, the contextual information also includes software and hardware states of the user device at the time the user request is received, and/or information related to the surrounding environment of the user at the time that the user request was received. In some examples, I/O processing module 728 also sends follow-up questions to, and receive answers from, the user regarding the user request. When a user request is received by I/O processing module 728 and the user request includes speech input, I/O processing module 728 forwards the speech input to STT processing module 730 (or speech recognizer) for speech-to-text conversions.

STT processing module 730 includes one or more ASR systems 758. The one or more ASR systems 758 can process the speech input that is received through I/O processing module 728 to produce a recognition result. Each ASR system 758 includes a front-end speech pre-processor. The front-end speech pre-processor extracts representative features from the speech input. For example, the front-end speech pre-processor performs a Fourier transform on the speech input to extract spectral features that characterize the speech input as a sequence of representative multi-dimensional vectors. Further, each ASR system 758 includes one or more speech recognition models (e.g., acoustic models and/or language models) and implements one or more speech recognition engines. Examples of speech recognition models include Hidden Markov Models, Gaussian-Mixture Models, Deep Neural Network Models, n-gram language models, and other statistical models. Examples of speech recognition engines include the dynamic time warping based engines and weighted finite-state transducers (WFST) based engines. The one or more speech recognition models and the one or more speech recognition engines are used to process the extracted representative features of the front-end speech pre-processor to produce intermediate recognitions results (e.g., phonemes, phonemic strings, and sub-words), and ultimately, text recognition results (e.g., words, word strings, or sequence of tokens). In some examples, the speech input is processed at least partially by a third-party service or on the user's device (e.g., device 104, 200, 400, or 600) to produce the recognition result. Once STT processing module 730 produces recognition results containing a text string (e.g., words, or sequence of words, or sequence of tokens), the recognition result is passed to natural language processing module 732 for intent deduction. In some examples, STT processing module 730 produces multiple candidate text representations of the speech input. Each candidate text representation is a sequence of words or tokens corresponding to the speech input. In some examples, each candidate text representation is associated with a speech recognition confidence score. Based on the speech recognition confidence scores, STT processing module 730 ranks the candidate text representations and provides the n-best (e.g., n highest ranked) candidate text representation(s) to natural language processing module 732 for intent deduction, where n is a predetermined integer greater than zero. For example, in one example, only the highest ranked (n=1) candidate text representation is passed to natural language processing module 732 for intent deduction. In another example, the five highest ranked (n=5) candidate text representations are passed to natural language processing module 732 for intent deduction.

More details on the speech-to-text processing are described in U.S. Utility application Ser. No. 13/236,942 for “Consolidating Speech Recognition Results,” filed on Sep. 20, 2011, the entire disclosure of which is incorporated herein by reference.

In some examples, STT processing module 730 includes and/or accesses a vocabulary of recognizable words via phonetic alphabet conversion module 731. Each vocabulary word is associated with one or more candidate pronunciations of the word represented in a speech recognition phonetic alphabet. In particular, the vocabulary of recognizable words includes a word that is associated with a plurality of candidate pronunciations. For example, the vocabulary includes the word “tomato” that is associated with the candidate pronunciations of /

/ and /

/. Further, vocabulary words are associated with custom candidate pronunciations that are based on previous speech inputs from the user. Such custom candidate pronunciations are stored in STT processing module 730 and are associated with a particular user via the user's profile on the device. In some examples, the candidate pronunciations for words are determined based on the spelling of the word and one or more linguistic and/or phonetic rules. In some examples, the candidate pronunciations are manually generated, e.g., based on known canonical pronunciations.

In some examples, the candidate pronunciations are ranked based on the commonness of the candidate pronunciation. For example, the candidate pronunciation /

/ is ranked higher than /

/, because the former is a more commonly used pronunciation (e.g., among all users, for users in a particular geographical region, or for any other appropriate subset of users). In some examples, candidate pronunciations are ranked based on whether the candidate pronunciation is a custom candidate pronunciation associated with the user. For example, custom candidate pronunciations are ranked higher than canonical candidate pronunciations. This can be useful for recognizing proper nouns having a unique pronunciation that deviates from canonical pronunciation. In some examples, candidate pronunciations are associated with one or more speech characteristics, such as geographic origin, nationality, or ethnicity. For example, the candidate pronunciation /

/ is associated with the United States, whereas the candidate pronunciation /

/ is associated with Great Britain. Further, the rank of the candidate pronunciation is based on one or more characteristics (e.g., geographic origin, nationality, ethnicity, etc.) of the user stored in the user's profile on the device. For example, it can be determined from the user's profile that the user is associated with the United States. Based on the user being associated with the United States, the candidate pronunciation /

/ (associated with the United States) is ranked higher than the candidate pronunciation /

/ (associated with Great Britain). In some examples, one of the ranked candidate pronunciations is selected as a predicted pronunciation (e.g., the most likely pronunciation).

When a speech input is received, STT processing module 730 is used to determine the phonemes corresponding to the speech input (e.g., using an acoustic model), and then attempt to determine words that match the phonemes (e.g., using a language model). For example, if STT processing module 730 first identifies the sequence of phonemes /

/ corresponding to a portion of the speech input, it can then determine, based on vocabulary index 744, that this sequence corresponds to the word “tomato.”

In some examples, STT processing module 730 uses approximate matching techniques to determine words in an utterance. Thus, for example, the STT processing module 730 determines that the sequence of phonemes /

/ corresponds to the word “tomato,” even if that particular sequence of phonemes is not one of the candidate sequence of phonemes for that word.

Natural language processing module 732 (“natural language processor”) of the digital assistant takes the n-best candidate text representation(s) (“word sequence(s)” or “token sequence(s)”) generated by STT processing module 730, and attempts to associate each of the candidate text representations with one or more “actionable intents” recognized by the digital assistant. An “actionable intent” (or “user intent”) represents a task that can be performed by the digital assistant, and can have an associated task flow implemented in task flow models 754. The associated task flow is a series of programmed actions and steps that the digital assistant takes in order to perform the task. The scope of a digital assistant's capabilities is dependent on the number and variety of task flows that have been implemented and stored in task flow models 754, or in other words, on the number and variety of “actionable intents” that the digital assistant recognizes. The effectiveness of the digital assistant, however, also dependents on the assistant's ability to infer the correct “actionable intent(s)” from the user request expressed in natural language.

In some examples, in addition to the sequence of words or tokens obtained from STT processing module 730, natural language processing module 732 also receives contextual information associated with the user request, e.g., from I/O processing module 728. The natural language processing module 732 optionally uses the contextual information to clarify, supplement, and/or further define the information contained in the candidate text representations received from STT processing module 730. The contextual information includes, for example, user preferences, hardware, and/or software states of the user device, sensor information collected before, during, or shortly after the user request, prior interactions (e.g., dialogue) between the digital assistant and the user, and the like. As described herein, contextual information is, in some examples, dynamic, and changes with time, location, content of the dialogue, and other factors.

In some examples, the natural language processing is based on, e.g., ontology 760. Ontology 760 is a hierarchical structure containing many nodes, each node representing either an “actionable intent” or a “property” relevant to one or more of the “actionable intents” or other “properties.” As noted above, an “actionable intent” represents a task that the digital assistant is capable of performing, i.e., it is “actionable” or can be acted on. A “property” represents a parameter associated with an actionable intent or a sub-aspect of another property. A linkage between an actionable intent node and a property node in ontology 760 defines how a parameter represented by the property node pertains to the task represented by the actionable intent node.

In some examples, ontology 760 is made up of actionable intent nodes and property nodes. Within ontology 760, each actionable intent node is linked to one or more property nodes either directly or through one or more intermediate property nodes. Similarly, each property node is linked to one or more actionable intent nodes either directly or through one or more intermediate property nodes. For example, as shown in FIG. 7C, ontology 760 includes a “restaurant reservation” node (i.e., an actionable intent node). Property nodes “restaurant,” “date/time” (for the reservation), and “party size” are each directly linked to the actionable intent node (i.e., the “restaurant reservation” node).

In addition, property nodes “cuisine,” “price range,” “phone number,” and “location” are sub-nodes of the property node “restaurant,” and are each linked to the “restaurant reservation” node (i.e., the actionable intent node) through the intermediate property node “restaurant.” For another example, as shown in FIG. 7C, ontology 760 also includes a “set reminder” node (i.e., another actionable intent node). Property nodes “date/time” (for setting the reminder) and “subject” (for the reminder) are each linked to the “set reminder” node. Since the property “date/time” is relevant to both the task of making a restaurant reservation and the task of setting a reminder, the property node “date/time” is linked to both the “restaurant reservation” node and the “set reminder” node in ontology 760.

An actionable intent node, along with its linked property nodes, is described as a “domain.” In the present discussion, each domain is associated with a respective actionable intent, and refers to the group of nodes (and the relationships there between) associated with the particular actionable intent. For example, ontology 760 shown in FIG. 7C includes an example of restaurant reservation domain 762 and an example of reminder domain 764 within ontology 760. The restaurant reservation domain includes the actionable intent node “restaurant reservation,” property nodes “restaurant,” “date/time,” and “party size,” and sub-property nodes “cuisine,” “price range,” “phone number,” and “location.” Reminder domain 764 includes the actionable intent node “set reminder,” and property nodes “subject” and “date/time.” In some examples, ontology 760 is made up of many domains. Each domain shares one or more property nodes with one or more other domains. For example, the “date/time” property node is associated with many different domains (e.g., a scheduling domain, a travel reservation domain, a movie ticket domain, etc.), in addition to restaurant reservation domain 762 and reminder domain 764.

While FIG. 7C illustrates two example domains within ontology 760, other domains include, for example, “find a movie,” “initiate a phone call,” “find directions,” “schedule a meeting,” “send a message,” and “provide an answer to a question,” “read a list,” “providing navigation instructions,” “provide instructions for a task” and so on. A “send a message” domain is associated with a “send a message” actionable intent node, and further includes property nodes such as “recipient(s),” “message type,” and “message body.” The property node “recipient” is further defined, for example, by the sub-property nodes such as “recipient name” and “message address.”

In some examples, ontology 760 includes all the domains (and hence actionable intents) that the digital assistant is capable of understanding and acting upon. In some examples, ontology 760 is modified, such as by adding or removing entire domains or nodes, or by modifying relationships between the nodes within the ontology 760.

In some examples, nodes associated with multiple related actionable intents are clustered under a “super domain” in ontology 760. For example, a “travel” super-domain includes a cluster of property nodes and actionable intent nodes related to travel. The actionable intent nodes related to travel includes “airline reservation,” “hotel reservation,” “car rental,” “get directions,” “find points of interest,” and so on. The actionable intent nodes under the same super domain (e.g., the “travel” super domain) have many property nodes in common. For example, the actionable intent nodes for “airline reservation,” “hotel reservation,” “car rental,” “get directions,” and “find points of interest” share one or more of the property nodes “start location,” “destination,” “departure date/time,” “arrival date/time,” and “party size.”

In some examples, each node in ontology 760 is associated with a set of words and/or phrases that are relevant to the property or actionable intent represented by the node. The respective set of words and/or phrases associated with each node are the so-called “vocabulary” associated with the node. The respective set of words and/or phrases associated with each node are stored in vocabulary index 744 in association with the property or actionable intent represented by the node. For example, returning to FIG. 7B, the vocabulary associated with the node for the property of “restaurant” includes words such as “food,” “drinks,” “cuisine,” “hungry,” “eat,” “pizza,” “fast food,” “meal,” and so on. For another example, the vocabulary associated with the node for the actionable intent of “initiate a phone call” includes words and phrases such as “call,” “phone,” “dial,” “ring,” “call this number,” “make a call to,” and so on. The vocabulary index 744 optionally includes words and phrases in different languages.

Natural language processing module 732 receives the candidate text representations (e.g., text string(s) or token sequence(s)) from STT processing module 730, and for each candidate representation, determines what nodes are implicated by the words in the candidate text representation. In some examples, if a word or phrase in the candidate text representation is found to be associated with one or more nodes in ontology 760 (via vocabulary index 744), the word or phrase “triggers” or “activates” those nodes. Based on the quantity and/or relative importance of the activated nodes, natural language processing module 732 selects one of the actionable intents as the task that the user intended the digital assistant to perform. In some examples, the domain that has the most “triggered” nodes is selected. In some examples, the domain having the highest confidence value (e.g., based on the relative importance of its various triggered nodes) is selected. In some examples, the domain is selected based on a combination of the number and the importance of the triggered nodes. In some examples, additional factors are considered in selecting the node as well, such as whether the digital assistant has previously correctly interpreted a similar request from a user.

User data 748 includes user-specific information, such as user-specific vocabulary, user preferences, user address, user's default and secondary languages, user's contact list, and other short-term or long-term information for each user. In some examples, natural language processing module 732 uses the user-specific information to supplement the information contained in the user input to further define the user intent. For example, for a user request “invite my friends to my birthday party,” natural language processing module 732 is able to access user data 748 to determine who the “friends” are and when and where the “birthday party” would be held, rather than requiring the user to provide such information explicitly in his/her request.

It should be recognized that in some examples, natural language processing module 732 is implemented using one or more machine learning mechanisms (e.g., neural networks). In particular, the one or more machine learning mechanisms are configured to receive a candidate text representation and contextual information associated with the candidate text representation. Based on the candidate text representation and the associated contextual information, the one or more machine learning mechanisms are configured to determine intent confidence scores over a set of candidate actionable intents. Natural language processing module 732 can select one or more candidate actionable intents from the set of candidate actionable intents based on the determined intent confidence scores. In some examples, an ontology (e.g., ontology 760) is also used to select the one or more candidate actionable intents from the set of candidate actionable intents.

Other details of searching an ontology based on a token string are described in U.S. Utility application Ser. No. 12/341,743 for “Method and Apparatus for Searching Using An Active Ontology,” filed Dec. 22, 2008, the entire disclosure of which is incorporated herein by reference.

In some examples, once natural language processing module 732 identifies an actionable intent (or domain) based on the user request, natural language processing module 732 generates a structured query to represent the identified actionable intent. In some examples, the structured query includes parameters for one or more nodes within the domain for the actionable intent, and at least some of the parameters are populated with the specific information and requirements specified in the user request. For example, the user says “Make me a dinner reservation at a sushi place at 7.” In this case, natural language processing module 732 is able to correctly identify the actionable intent to be “restaurant reservation” based on the user input. According to the ontology, a structured query for a “restaurant reservation” domain includes parameters such as {Cuisine}, {Time}, {Date}, {Party Size}, and the like. In some examples, based on the speech input and the text derived from the speech input using STT processing module 730, natural language processing module 732 generates a partial structured query for the restaurant reservation domain, where the partial structured query includes the parameters {Cuisine=“Sushi”} and {Time=“7 pm”}. However, in this example, the user's utterance contains insufficient information to complete the structured query associated with the domain. Therefore, other necessary parameters such as {Party Size} and {Date} are not specified in the structured query based on the information currently available. In some examples, natural language processing module 732 populates some parameters of the structured query with received contextual information. For example, in some examples, if the user requested a sushi restaurant “near me,” natural language processing module 732 populates a {location} parameter in the structured query with GPS coordinates from the user device.

In some examples, natural language processing module 732 identifies multiple candidate actionable intents for each candidate text representation received from STT processing module 730. Further, in some examples, a respective structured query (partial or complete) is generated for each identified candidate actionable intent. Natural language processing module 732 determines an intent confidence score for each candidate actionable intent and ranks the candidate actionable intents based on the intent confidence scores. In some examples, natural language processing module 732 passes the generated structured query (or queries), including any completed parameters, to task flow processing module 736 (“task flow processor”). In some examples, the structured query (or queries) for the m-best (e.g., m highest ranked) candidate actionable intents are provided to task flow processing module 736, where m is a predetermined integer greater than zero. In some examples, the structured query (or queries) for the m-best candidate actionable intents are provided to task flow processing module 736 with the corresponding candidate text representation(s).

Other details of inferring a user intent based on multiple candidate actionable intents determined from multiple candidate text representations of a speech input are described in U.S. Utility application Ser. No. 14/298,725 for “System and Method for Inferring User Intent From Speech Inputs,” filed Jun. 6, 2014, the entire disclosure of which is incorporated herein by reference.

Task flow processing module 736 is configured to receive the structured query (or queries) from natural language processing module 732, complete the structured query, if necessary, and perform the actions required to “complete” the user's ultimate request. In some examples, the various procedures necessary to complete these tasks are provided in task flow models 754. In some examples, task flow models 754 include procedures for obtaining additional information from the user and task flows for performing actions associated with the actionable intent.

As described above, in order to complete a structured query, task flow processing module 736 needs to initiate additional dialogue with the user in order to obtain additional information, and/or disambiguate potentially ambiguous utterances. When such interactions are necessary, task flow processing module 736 invokes dialogue flow processing module 734 to engage in a dialogue with the user. In some examples, dialogue flow processing module 734 determines how (and/or when) to ask the user for the additional information and receives and processes the user responses. The questions are provided to and answers are received from the users through I/O processing module 728. In some examples, dialogue flow processing module 734 presents dialogue output to the user via audio and/or visual output, and receives input from the user via spoken or physical (e.g., clicking) responses. Continuing with the example above, when task flow processing module 736 invokes dialogue flow processing module 734 to determine the “party size” and “date” information for the structured query associated with the domain “restaurant reservation,” dialogue flow processing module 734 generates questions such as “For how many people?” and “On which day?” to pass to the user. Once answers are received from the user, dialogue flow processing module 734 then populates the structured query with the missing information, or pass the information to task flow processing module 736 to complete the missing information from the structured query.

Once task flow processing module 736 has completed the structured query for an actionable intent, task flow processing module 736 proceeds to perform the ultimate task associated with the actionable intent. Accordingly, task flow processing module 736 executes the steps and instructions in the task flow model according to the specific parameters contained in the structured query. For example, the task flow model for the actionable intent of “restaurant reservation” includes steps and instructions for contacting a restaurant and actually requesting a reservation for a particular party size at a particular time. For example, using a structured query such as: {restaurant reservation, restaurant=ABC Café, date=3/12/2012, time=7 pm, party size=5}, task flow processing module 736 performs the steps of: (1) logging onto a server of the ABC Café or a restaurant reservation system such as OPENTABLE®, (2) entering the date, time, and party size information in a form on the website, (3) submitting the form, and (4) making a calendar entry for the reservation in the user's calendar.

In some examples, task flow processing module 736 employs the assistance of service processing module 738 (“service processing module”) to complete a task requested in the user input or to provide an informational answer requested in the user input. For example, service processing module 738 acts on behalf of task flow processing module 736 to make a phone call, set a calendar entry, invoke a map search, invoke or interact with other user applications installed on the user device, and invoke or interact with third-party services (e.g., a restaurant reservation portal, a social networking website, a banking portal, etc.). In some examples, the protocols and application programming interfaces (API) required by each service are specified by a respective service model among service models 756. Service processing module 738 accesses the appropriate service model for a service and generates requests for the service in accordance with the protocols and APIs required by the service according to the service model.

For example, if a restaurant has enabled an online reservation service, the restaurant submits a service model specifying the necessary parameters for making a reservation and the APIs for communicating the values of the necessary parameter to the online reservation service. When requested by task flow processing module 736, service processing module 738 establishes a network connection with the online reservation service using the web address stored in the service model, and sends the necessary parameters of the reservation (e.g., time, date, party size) to the online reservation interface in a format according to the API of the online reservation service.

In some examples, natural language processing module 732, dialogue flow processing module 734, and task flow processing module 736 are used collectively and iteratively to infer and define the user's intent, obtain information to further clarify and refine the user intent, and finally generate a response (i.e., an output to the user, or the completion of a task) to fulfill the user's intent. The generated response is a dialogue response to the speech input that at least partially fulfills the user's intent. Further, in some examples, the generated response is output as a speech output. In these examples, the generated response is sent to speech synthesis processing module 740 (e.g., speech synthesizer) where it can be processed to synthesize the dialogue response in speech form. In yet other examples, the generated response is data content relevant to satisfying a user request in the speech input.

In examples where task flow processing module 736 receives multiple structured queries from natural language processing module 732, task flow processing module 736 initially processes the first structured query of the received structured queries to attempt to complete the first structured query and/or execute one or more tasks or actions represented by the first structured query. In some examples, the first structured query corresponds to the highest ranked actionable intent. In other examples, the first structured query is selected from the received structured queries based on a combination of the corresponding speech recognition confidence scores and the corresponding intent confidence scores. In some examples, if task flow processing module 736 encounters an error during processing of the first structured query (e.g., due to an inability to determine a necessary parameter), the task flow processing module 736 can proceed to select and process a second structured query of the received structured queries that corresponds to a lower ranked actionable intent. The second structured query is selected, for example, based on the speech recognition confidence score of the corresponding candidate text representation, the intent confidence score of the corresponding candidate actionable intent, a missing necessary parameter in the first structured query, or any combination thereof.

Speech synthesis processing module 740 is configured to synthesize speech outputs for presentation to the user. Speech synthesis processing module 740 synthesizes speech outputs based on text provided by the digital assistant. For example, the generated dialogue response is in the form of a text string. Speech synthesis processing module 740 converts the text string to an audible speech output. Speech synthesis processing module 740 uses any appropriate speech synthesis technique in order to generate speech outputs from text, including, but not limited, to concatenative synthesis, unit selection synthesis, diphone synthesis, domain-specific synthesis, formant synthesis, articulatory synthesis, hidden Markov model (HMM) based synthesis, and sinewave synthesis. In some examples, speech synthesis processing module 740 is configured to synthesize individual words based on phonemic strings corresponding to the words. For example, a phonemic string is associated with a word in the generated dialogue response. The phonemic string is stored in metadata associated with the word. Speech synthesis processing module 740 is configured to directly process the phonemic string in the metadata to synthesize the word in speech form.

In some examples, instead of (or in addition to) using speech synthesis processing module 740, speech synthesis is performed on a remote device (e.g., the server system 108), and the synthesized speech is sent to the user device for output to the user. For example, this can occur in some implementations where outputs for a digital assistant are generated at a server system. And because server systems generally have more processing power or resources than a user device, it is possible to obtain higher quality speech outputs than would be practical with client-side synthesis.

Additional details on digital assistants can be found in the U.S. Utility application Ser. No. 12/987,982, entitled “Intelligent Automated Assistant,” filed Jan. 10, 2011, and U.S. Utility application Ser. No. 13/251,088, entitled “Generating and Processing Task Items That Represent Tasks to Perform,” filed Sep. 30, 2011, the entire disclosures of which are incorporated herein by reference.

4. Delivering Content for User Experiences

FIGS. 8-18 illustrate various electronic devices of an environment and exemplary user interfaces of the electronic devices, according to various examples. These figures are also used to illustrate one or more of the processes described below, including processes 1900 and 2000 of FIGS. 19 and 20, respectfully.

FIGS. 8-18 illustrates an electronic device. For example, as shown in FIG. 8A, the electronic device 800 may be any device described herein, including but not limited to devices 104, 200, 400, and 600 (FIGS. 1, 2A, 4, and 6A-B). Thus, while the electronic device 800 is depicted as a mobile device, it will be appreciated that the electronic device 800 may be a device of any type, such as a phone, laptop computer, desktop computer, tablet, wearable device (e.g., smart watch), set-top box, television, home automation device (e.g., thermostat), or any combination or subcombination thereof. Furthermore, the processes described herein may be performed by a server with information delivered to and from the device, performed on the device, or a combination thereof.

In operation, the electronic device 800 receives a user input 802 from a user of the electronic device 800. The user input 802 may be a user input of any type including, but not limited to, a touch input, a speech input (e.g., natural-language speech input), a switch input (e.g., a user toggles a physical switch of the electronic device), and/or a typed input (e.g., user enters text using a keyboard interfaced with the electronic device 800).

In some examples, the user input 802 includes a plurality of words. In the illustrated example, a user input received by the electronic device 800 includes the words “Show my trip to Hawaii last April.” The user input “Show my trip to Hawaii last April” may be associated with a natural-language speech input, for example. In some examples, a representation 804 of the input is displayed on a display (e.g., touch sensitive display) of the electronic device 800.

In some examples, the electronic device 800 determines whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In some examples, user intent is determined based on the existence of specific vocabulary contained within the speech input. For example, the use of photo or video nouns, such as “pictures,” “photos,” “videos,” “clips,” “pics,” and the like, may be used to determine whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In some examples, the use of semantic terms related to a user experience, such as “memories” or “highlights” may be used to determine whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In yet other examples, the use of past activity verbs, such as “did” “went,” “saw, or “traveled,” “dined” may be used to determine whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In other examples, the use of search verbs, such as “find,” “locate” “pull up,” “what was,” or “where was,” may be used to determine whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In some examples, a reference to a point in time may be used to determine whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. For example, with reference to the user speech input of “Show my trip to Hawaii last April with John,” the reference to “John,” may be used to determine whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, as opposed to an intent for a general search. In some examples, device 800 may determine that the word “Show” in the user input 802 “Show my trip to Hawaii last April” corresponds to a search verb, and the word “trip” corresponds to a semantic term related to a user experience.

In some examples, in response to a determination that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, device 800 identifies, from the speech input, one or more parameters referencing a user experience of the user. The one or more parameters referencing a user experience of a user may include at least one parameter type. In some examples, the parameter type may include a type for “event,” a type for “activity”, a type for “geographical feature, a type for “person,” a type for “place,” a type for “time,” and/or a type for “location.” In some examples, a type for “event” may be associated with a user experience for a trip, vacation, party, birthday, wedding, graduation, social event, or other events. In some examples, a type for “activity” may be associated with a user experience corresponding to running, skiing, camping, rafting, biking, hiking, riding, another workout, or other physical activities. In some examples, a type for “geographical feature” may be associated with a user experience corresponding to a beach, sand, mountains, a volcano, a lake, a river, an island, or any other geographical feature. In some examples, a type for “person” may be associated with a user experience in which another individual shared the same experience with the user. In some examples, the individual may be referred to by full name, nickname, or another reference to the individual. In some examples, a type for “place” may be associated with a user experience corresponding to a specific location or destination, such as a restaurant, hospital, hotel, bar, nightclub, golf club, park, or any other place. For example, device 800 may determine that the word “Hawaii” in the user input corresponds to a “place” type parameter. In some examples, a type for “time” may be associated with a user experience that occurred at a specific hour of a day, specific days during the week, specific reoccurring days of a year (e.g., all Thanksgivings), and the like. In some examples, a type for “location” may be associated with one or more locations associated with the user experience, such as a venue, a city, a state, and/or a country.

The one or more parameters referencing a user experience of a user may further include a sub-parameter type. In some examples, the sub-parameter type may include a sub-type corresponding to a type for “place,” such as the name of a store. For example, a parameter for a “place” type may include “grocery store,” and a parameter for the “place” sub-type may include “Nob Hill Foods.” As another example, a parameter for a “place” type may include “coffee shop,” and a parameter for the “place” sub-type may include “Starbucks.” As yet another example, a parameter for a “place” type may include “restaurant,” and a parameter for the “place” sub-type may include “Chinese” or “Italian.” The one or more parameters referencing a user experience of a user may further include a parameter descriptor type. In some examples, a parameter for an “activity” may include a “run,” and a parameter for the “activity” descriptor may include “long” or “short.” In some examples, a parameter for a “place” may include “store,” and a parameter for the “place” descriptor may include “busy” or “big.”

In some examples, device 800 obtains, from an experiential data structure, metadata associated with the referenced user experience. The experiential data structure may be generated based on at least one pattern recognition process, for example. In some examples, the experiential data structure is generated, updated, and/or maintained by one or more pattern recognition components and/or one or more graph processing components. In some examples, based on the user input “Show my trip to Hawaii last April,” device 800 may obtain, from an experiential data structure, metadata associated with a “trip” to “Hawaii” during the month of “April” of the preceding year. In some examples, obtaining metadata associated with the referenced user experience includes querying one or more applications associated with device 800, the querying including sending one or more requests to the one or more applications for metadata associated with one or more parameters, such as parameters or a referenced event, activity, geographical feature, person, and/or place. In some examples, obtaining metadata associated with the referenced user experience includes querying, by one or more applications associated with device 800, the one or more pattern recognition components and/or one or more graph processing components. The querying may include sending a request to one or more API or SPI components to obtain metadata associated with specific parameters, such as parameters or a referenced event, activity, geographical feature, person, and/or place. The querying may further be associated with a time range, date range, or any other sub-type or descriptor associated with requested parameters. For example, a query may include an event parameter for “trip,” a place parameter for “Hawaii,” and sub-type parameter for “April” of the preceding year.

In some examples, device 800 retrieves, based on the metadata associated with the referenced user experience, one or more media items associated with the referenced user experience. For example, device 800 may retrieve pictures, videos, music, or any other media items associated with the user experience corresponding to the “trip to Hawaii last April.” In some examples, a media application obtains media associated with a user profile, such as media generated by the user during the referenced user experience. In some examples, the media application obtains media associated with a user profile, and generated by the user proximate to, but not during, the referenced user experience. In some examples, the media application obtains media items from a remote source, such as the Internet, when one or more predetermined criteria are satisfied. For example, if location data on the device determines that the user visited the Haleakala National Park, but the user did not generate any media while at the location, stock images of the Haleakalā volcano may be obtained from the Internet. In other examples, media items may be obtained from a remote source where there is a small amount of user-generated media for a referenced user experience.

In some examples, device 800 outputs together the one or more media items associated with the referenced user experience. As shown in FIG. 8A, for example, device 800 outputs an affordance 806 to allow a user to select the one or more media items and the information associated with the referenced user experience. As shown in FIG. 8B, for example, selection of affordance 806 invokes a media application for an interactive display 810 of the one or more media items. In some examples, the outputting together one or more media items associated with the referenced user experience includes generating information associated with the referenced user experience and displaying the generated information together with the one or more media items. For example, in response to the user input “Show my trip to Hawaii last year,” device 800 may utilize a maps application to generate map information corresponding to location metadata associated with the “trip to Hawaii.” In another example, device 800 may utilize a third party review application to generate business location information corresponding to location metadata associated with the “trip to Hawaii.” In yet another example, device 800 may utilize a messaging application to generate messaging information corresponding to message metadata associated with the “trip to Hawaii.”

In some examples, outputting together one or more media items associated with the referenced user experience includes automatically outputting the interactive display 810, without user interaction of an affordance. In some examples, the interactive display 810 includes a summary portion 812. For example, the summary portion 812 may include a title of the referenced user experience, a date range of the user experience, and a representation of one or more participants of the user experience. In some examples, the interactive display 810 is partitioned by time, such that media items and information associated with the user experience are clustered together by minute, hour, day, week, month, year, and the like. For example, time segment 814 may indicate a specific time associated with the referenced user experience, and location information 816 may correspond to time segment 814. In some examples, location information 816 may depict device location information corresponding to the time represented by time segment 814.

In some examples, as shown in FIG. 8C, interactive display 810 permits a user to obtain additional media items and information via the display using at least one gesture input. For example, a user may perform a finger swipe gesture in direction 818 in order to scroll through additional media items and information provided on the interactive display 810. In some examples, additional media items 820 associated with time segment 814 are displayed in response to a user gesture to obtain additional media items and information. In some examples, additional information 822 associated with time segment 814 is displayed in response to a user gesture to obtain additional media items and information. For example, information 822 may correspond to device location information, and/or one or more reviews of a venue visited by the user.

In some examples, as shown in FIG. 8D, a user may perform additional gestures to obtain additional media items and information via interactive display 810. For example, additional information may include a representation of one or more messages corresponding to time segment 814, media items 820, and/or information 822. For example, instant messages related to a dinner reservation may be displayed, which correspond to time segment 814 and information 822 including device location information. In some examples, one or more additional time segments 826 may be displayed to indicate a specific time associated with the referenced user experience. In some examples, the one or more additional time segments may be associated with additional media item and information associated with the additional time segment, such as location information 828 associated with time segment 826.

In some examples, as shown in FIG. 8E, the speech input may refer to a plurality of user experiences. For example, the speech input 830 may include “Show my trip to Hawaii.” According to the processes discussed with respect to FIGS. 8A-8D, media items and/or information corresponding to a plurality of user experiences for trips to Hawaii may be retrieved and/or generated. In some examples, a plurality of affordances associated with the referenced user experiences may be output to the user. For example, an affordance 832 may correspond to a user's trip to Hawaii in April 2016, an affordance 834 may correspond to a user's trip to Hawaii in March 2014, and an affordance 832 may correspond to an earlier trip to Hawaii. In some examples, user selection of the one or more affordances may cause output together of the one or more media items associated with the selected user experience and generated information associated with the selected user experience.

FIG. 9 illustrates an electronic device 900. In operation, the electronic device 900 receives a user input 902 from a user of the electronic device 900. The user input 902 may be a user input of any type including, but not limited to, a touch input, a speech input (e.g., natural-language speech input), a switch input (e.g., a user toggles a physical switch of the electronic device), and/or a typed input (e.g., user enters text using a keyboard interfaced with the electronic device 900).

In some examples, the user input 902 includes a plurality of words. In the illustrated example, a user input received by the electronic device 900 includes the words “Show me some good memories.” The user input “Show me some good memories” may be associated with a natural-language speech input, for example. In some examples, a representation of the input (not depicted) is displayed on a display (e.g., touch sensitive display) of the electronic device 900.

In some examples, the electronic device 900 determines whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In some examples, device 900 may determine that the word “Show” in the user input 902 “Show me some good memories” corresponds to a search verb, and the word “memories” corresponds to a semantic term related to a user experience.

In some examples, in response to a determination that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, device 900 identifies, from the speech input, one or more parameters referencing a user experience of the user. In some examples, device 900 may determine that the speech input corresponds to a general request to obtain information associated with one or more random user experiences. For example, device 900 may determine that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, but the speech input does not include a parameter type for “event,” a type for “activity”, a type for “geographical feature, a type for “person,” and/or a type for “place.” In response to a determination that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, but the speech input does not include a defined parameter type, for example, device 900 may determine other parameters of the user input, such as a sub-type parameter or descriptor parameter referencing a user experience. For example, device 900 may determine that the speech input includes the descriptor parameter “good.” In some examples, device 900 may determine that the parameters of the speech input reference any user experience associated with a descriptor parameter for “good.”

In some examples, device 900 obtains, from an experiential data structure, metadata associated with the referenced user experience. For example, device 900 may obtain metadata associated with one or more user experiences associated with a descriptor parameter for “good.” In some examples, device 900 retrieves, based on the metadata associated with the referenced user experience, one or more media items associated with the referenced user experience. For example, device 900 may retrieve pictures, videos, music, or any other media items associated with the user experience corresponding to the one or more user experiences associated with a descriptor parameter for “good.” In some examples, device 900 generates, using the metadata, information associated with the referenced user experience. For example, in response to the user input “Show me some good memories,” device 900 may utilize a maps application or a music application to generate information for one or more user experiences associated with a descriptor parameter for “good,” such as a “good run” or a “good vacation.” In some examples, device 900 outputs a plurality of affordances 904 each representing a referenced user experience. For example, user activation of one of the plurality of affordances 904 may cause the output of one or more media items. For example, in response to the user activation of one of the plurality of affordances 904, device 900 outputs together the one or more media items associated with the referenced user experience.

FIG. 10 illustrates an electronic device 1000. In operation, the electronic device 1000 receives a user input 1002 from a user of the electronic device 1000. The user input 1002 may be a user input of any type including, but not limited to, a touch input, a speech input (e.g., natural-language speech input), a switch input (e.g., a user toggles a physical switch of the electronic device), and/or a typed input (e.g., user enters text using a keyboard interfaced with the electronic device 1000).

In some examples, the user input 1000 includes a plurality of words. In the illustrated example, a user input received by the electronic device 1000 includes the words “Show our visit to the museum in San Francisco.” The user input “Show our visit to the museum in San Francisco” may be associated with a natural-language speech input, for example. In some examples, a representation of the input (not depicted) is displayed on a display (e.g., touch sensitive display) of the electronic device 1000.

In some examples, the electronic device 1000 determines whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In some examples, device 1000 may determine that the word “Show” in the user input 1002 “Show our visit to the museum in San Francisco” corresponds to a search verb, the word “visit” corresponds to at least one verb for a past activity, and “museum” corresponds to a semantic term related to a user experience.

In some examples, in response to a determination that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, device 1000 identifies, from the speech input, one or more parameters referencing a user experience of the user. For example, device 1000 may determine that the words “museum” and “San Francisco” correspond to “place” type parameters, and the referenced user experience includes a recent user visit to an art museum in the city of San Francisco. In some examples, the one or more parameters may reference a plurality of user experiences each corresponding to the one or more parameters. For example, a user may have previously visited both an art museum and a history museum in the city of San Francisco. In some examples, when device 1000 determines that the one or more parameters reference a plurality of user experiences each corresponding to the one or more parameters, device 1000 disambiguates the speech input to determine a most relevant user experience. For example, device 1000 may output one or more clarification questions to the user, such as “Do you mean the visit to the art museum or the visit to the history museum?” In another example, device 1000 may use context information to determine which user experience the user is more likely to be referring to. For example, device 1000 may determine that the user's visit to the art museum occurred last week, and the visit to the history museum occurred over a year ago, and the user is therefore more likely to be referring to the user experience that occurred more recently, such as the visit to the art museum. In some examples, identifying, from the speech input, one or more parameters referencing a user experience of the user may include identifying one or more parameters referencing a plurality of user experiences of the user. For example, instead of disambiguating the speech input to determine a most relevant user experience from a plurality of user experiences, device 1000 may identify one or more parameters referencing a plurality of user experiences of the user. In some examples, device 1000 may display one or more thumbnail elements corresponding to the plurality of user experiences. For example, in response to being presented with a plurality of thumbnail elements corresponding to the plurality of referenced user experiences, the user may select a thumbnail corresponding to a user experience that the user wishes to view.

In some examples, device 1000 obtains, from an experiential data structure, metadata associated with the referenced user experience. In some examples, based on the user input “Show our visit to the museum in San Francisco,” device 800 may obtain, from an experiential data structure, metadata associated with the user's recent visit to the art museum in San Francisco. In some examples, obtaining metadata associated with the referenced user experience includes querying one or more applications associated with device 1000. For example, a query may include a place parameter for “museum,” a place parameter for “San Francisco.” In some examples, the query is sent to applications including a notes application in order to obtain metadata associated with notes created by the user and corresponding to the referenced user experience. For example, the user may have invoked the notes application while at the art museum, and created an entry in the notes application while at the museum.

In some examples, device 1000 retrieves, based on the metadata associated with the referenced user experience, one or more media items associated with the referenced user experience. For example, device 1000 may retrieve pictures, videos, music, or any other media items associated with the user experience corresponding to the user's recent visit to the art museum in San Francisco.

In some examples, device 1000 outputs together the one or more media items associated with the referenced user experience. As shown in FIG. 10, for example, device 1000 outputs one or more media items 1004 corresponding to a summary slideshow of pictures and/or videos automatically generated from selected pictures and/or videos taken during the user's visit to the museum. In some examples, device 1000 outputs one or more media items 1006 corresponding to individual still pictures, short animated pictures, and/or videos taken during the user's visit to the museum. In some examples, outputting together the one or more media items associated with the referenced user experience further includes generating, using the metadata, information associated with the referenced user experience and outputting the generated information associated with the referenced user experience together with the one or more media items. For example, device 1000 may utilize the notes metadata to generate notes that were taken by the user while at the art museum. In another example, device 1000 may utilize maps metadata to generate a map view of the art museum. For example, device 1000 outputs information 1008 corresponding to notes that were taken by the user while at the art museum. In some examples, device 1000 outputs location information corresponding to the museum within a map view (not depicted). In some examples, a user input, such as a gesture input, may cause additional media items and information to be displayed. For example, media items and information from a website corresponding to the user experience may be displayed, such as photos and general information from a website associated with the art museum.

FIG. 11 illustrates an electronic device 1100. In operation, the electronic device 1100 receives a user input 1102 from a user of the electronic device 1100. The user input 1102 may be a user input of any type including, but not limited to, a touch input, a speech input (e.g., natural-language speech input), a switch input (e.g., a user toggles a physical switch of the electronic device), and/or a typed input (e.g., user enters text using a keyboard interfaced with the electronic device 1100).

In some examples, the user input 1100 includes a plurality of words. In the illustrated example, a user input received by the electronic device 1100 includes the words “Show me memories with John Smith.” The user input “Show me memories with John Smith” may be associated with a natural-language speech input, for example. In some examples, a representation of the input (not depicted) is displayed on a display (e.g., touch sensitive display) of the electronic device 1100.

In some examples, the electronic device 1100 determines whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In some examples, device 1100 may determine that the word “Show” corresponds to a search verb, the words “memories” and “John Smith” correspond to semantics terms related to a user experience.

In some examples, in response to a determination that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, device 1100 identifies, from the speech input, one or more parameters referencing a user experience of the user. In some examples, device 1100 may determine that the words “John Smith” correspond to a “person” type parameter. For example, “John Smith” may be included as a contact in a contacts application on the device. As another example, the name “John Smith” may be referenced in one or more instant messages or e-mail messages associated with one or more user experiences. In some examples, a “person” type parameter may be determined based on a name typed by the user and associated with the photo, such as a name typed into the photo or typed into notes associated with the photo. In some examples, a “person” type parameter may be determined based on disambiguation using a contacts application. For example, in response to the speech input including the words “my mom” or “my soccer coach,” the words may be disambiguated using natural language processing to resolve the words to specific contacts in the contacts application.

In some examples, device 1100 obtains, from an experiential data structure, metadata associated with the referenced user experience. In some examples, metadata associated with the “person” type parameter “John Smith” is obtained. For example, metadata associated with calendar events having “John Smith” as an invitee or participant are obtained. As another example, messages or e-mails exchanged or otherwise associated with the contact “John Smith” are obtained. As yet another example, telephone or FaceTime sessions exchanged with “John Smith” are obtained. As yet another example, media such as pictures or video including “John Smith” are obtained, for example, using facial recognition. As yet another example, notes metadata including “John Smith” as text are obtained.

In some examples, device 1100 retrieves, based on the metadata associated with the referenced user experience, one or more media items associated with the referenced user experience. In some examples, the referenced user experience may include one or more links to other user experiences. For example, device 1100 may retrieve pictures, videos, music, or any other media items associated with all user experiences involving a referenced “person” parameter, such as “John Smith.” In some examples, device 1100 generates, using the metadata, information associated with the referenced user experience. For example, device 1100 may utilize a maps application to generate map information corresponding to location metadata associated with one or more user experiences involving the contact “John Smith.” As another example, device 1100 may utilize a third party review application to generate business location information corresponding to location metadata associated with one or more user experiences involving the contact “John Smith.” In yet another example, device 1100 may utilize a messaging application to generate messaging information corresponding to message metadata associated with one or more user experiences involving the contact “John Smith.”

In some examples, device 1100 outputs together the one or more media items associated with the referenced user experience. In some examples, prior to outputting together the one or more media items associated with the referenced user experience, device 1100 may output one or more links to a plurality of user experiences. As shown in FIG. 11, device 1100 may output links to a plurality of user experiences 1106, 1108, and 1110. In some examples, each user experience associated with links 1106, 1106, and 1110 correspond to user experiences with the contact “John Smith” 1104. In some examples, activation of links 1106, 1108, and 1110 may cause output together of the one or more media items associated with the referenced user experience corresponding to the activated link. In some examples, links 1106, 1108, and 1110 are displayed within a contacts application on device 1100. In some examples, outputting together the one or more media items associated with the referenced user experience further includes generating, using the metadata, information associated with the referenced user experience, and outputting the generated information together with the one or more media items. For example, device 1100 may display one or more affordances adjacent to contact 1104, where activation of the one or more affordances may cause a telephone call, FaceTime session, instant messaging session, or other activity to be invoked.

FIG. 12 illustrates an electronic device 1200. In operation, the electronic device 1200 receives a user input 1202 from a user of the electronic device 1200. The user input 1202 may be a user input of any type including, but not limited to, a touch input, a speech input (e.g., natural-language speech input), a switch input (e.g., a user toggles a physical switch of the electronic device), and/or a typed input (e.g., user enters text using a keyboard interfaced with the electronic device 1200).

In some examples, the user input 1202 includes a plurality of words. In the illustrated example, a user input received by the electronic device 1200 includes the words “Show the run I took in Point Lobos.” The user input “Show the run I took in Point Lobos” may be associated with a natural-language speech input, for example. In some examples, a representation of the input (not depicted) is displayed on a display (e.g., touch sensitive display) of the electronic device 1200.

In some examples, the electronic device 1200 determines whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In some examples, device 1200 may determine that the word “Show” corresponds to a search verb, the words “run” and “Point Lobos” correspond to semantics terms related to a user experience, and the word “took” corresponds to a past activity verb.

In some examples, in response to a determination that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, device 1200 identifies, from the speech input, one or more parameters referencing a user experience of the user. For example, device 1200 may determine that the word “Point Lobos” in the user input corresponds to a “place” type parameter, and the word “run” corresponds to an “activity” type parameter.

In some examples, device 1200 obtains, from an experiential data structure, metadata associated with the referenced user experience. For example, a query may include an activity parameter for a “run,” and a place parameter for “Point Lobos.” In some examples, device 1200 may query an activity application using the parameters. For example, an activity application may store one or more activities logged by the user during one or more runs, bikes, hikes, walks, or other workout sessions. Using the parameters, for example, the activity application may be queried for metadata corresponding to a running activity that occurred at or near the location corresponding to “Point Lobos.” In some examples, when device 1200 determines that the one or more parameters reference a plurality of user experiences each corresponding to the one or more parameters, device 1200 disambiguates the speech input to determine a most relevant user experience. For example, the user may have logged a running session in Point Lobos on multiple occasions. In that case, for example, device 1020 may output one or more clarification questions to the user, such as “Do you mean the run in Point Lobos on April 30th or April 10th?” In another example, device 1200 may use context information to determine which user experience the user is more likely to be referring to. For example, device 1200 may determine that the user most recently logged a running session in Point Lobos last week and the next most recently logged running session in Point Lobos occurred over a year ago, and therefore the user is more likely to be referring to the user experience that occurred more recently, such as the running session in Point Lobos last week. In some examples, device 1200 may display one or more thumbnail elements corresponding to a plurality of referenced user experiences. For example, in response to being presented with a plurality of thumbnail elements corresponding to the plurality of referenced user experiences, the user may select a thumbnail corresponding to a user experience that the user wishes to view. In some examples, the metadata associated with the referenced user experience may be obtained from a secondary device. For example, metadata may be obtained from devices such as the Apple Watch®, a third party fitness device, or any other device including metadata associated with the referenced experience.

In some examples, device 1200 retrieves, based on the metadata associated with the referenced user experience, one or more media items associated with the referenced user experience. For example, device 1200 may retrieve pictures, videos, music, or any other media items associated with the user experience corresponding to the user's logged run in Point Lobos. In some examples, a media application obtains media associated with a user profile, such as media generated by the user during the referenced user experience. In some examples, the media may have been taken captured device 1200 or with a secondary device. For example, if a user used a secondary device (e.g., a camera or video recorder) to capture media during the logged activity, one or more media items captured on the secondary device may be retrieved. In some examples, the one or more media items captured on the secondary device may be retrieved based on a user profile of the user, for example, from a remote server in communication with device 1200. In some examples, the one or more media items captured on the secondary device may be retrieved based on one or more timestamps associated with the one or more media items.

In some examples, device 1200 outputs together the one or more media items associated with the referenced user experience. As shown in FIG. 12, for example, device 1200 outputs an interactive display of the one or more media items. In some examples, device 1200 generates, using the metadata, information associated with the referenced user experience and outputs the generated information together with the one or more media items. For example, in response to the user input “Show the run I took in Point Lobos,” device 1200 may utilize a maps application to generate map information corresponding to location metadata associated with the user's logged run in Point Lobos. Using location metadata, for example, the maps application may generate map information indicating the running route the user took during the logged session. In another example, device 1200 may utilize an activity application to generate activity statistics associated with the user's logged run in Point Lobos. Using activity metadata, for example, the activity application may generate information statistics associated with the logged run, including but not limited to heart rate information, distance information, pace information, splits information, elevation information, calorie information, steps information, timing information, and the like. In some examples, the interactive display includes a summary portion 1204. For example, the summary portion 1204 may include a title of the referenced user experience, such as “Running,” a time, date, time range or date range of the user experience, such as “Aug. 15, 2016-3:33 PM.” In some examples, the summary portion 1204 may include an activity summary, including total miles traveled or total calories burned, such as “34 miles.” In some examples, the interactive display includes location information associated with the referenced user experience. For example, generated map information 1206 corresponding to the user's run in Point Lobos may be displayed. In some examples, the one or more media items may be output proximate to the information associated with the reference user experience. For example, one or more media items 1208 may be displayed below the generated map information 1206. In some examples, a user input, such as a gesture input, may cause the display to scroll upwards or downward to output additional media items and generated information associated with the referenced user experience (not depicted), such as health information, other participant information, calendar information, and the like.

FIG. 13 illustrates an electronic device 1300. In operation, the electronic device 1300 receives a user input 1302 from a user of the electronic device 1300. The user input 1302 may be a user input of any type including, but not limited to, a touch input, a speech input (e.g., natural-language speech input), a switch input (e.g., a user toggles a physical switch of the electronic device), and/or a typed input (e.g., user enters text using a keyboard interfaced with the electronic device 1300).

In some examples, the user input 1302 includes a plurality of words. In the illustrated example, a user input received by the electronic device 1300 includes the words “What was the seafood restaurant in Monterey.” The user input “What was the seafood restaurant in Monterey” may be associated with a natural-language speech input, for example. In some examples, a representation of the input (not depicted) is displayed on a display (e.g., touch sensitive display) of the electronic device 1300.

In some examples, the electronic device 1300 determines whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In some examples, device 1300 may determine that the words “What was” corresponds to a search verb, the words “restaurant” and “Monterey” correspond to semantics terms related to a user experience.

In some examples, in response to a determination that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, device 1300 identifies, from the speech input, one or more parameters referencing a user experience of the user. For example, device 1300 may determine that the words “restaurant” and “Monterey each correspond to a “place” type parameter, and the word “seafood” corresponds to a sub-type parameter for the “place” parameter corresponding to “restaurant.”

In some examples, device 1300 obtains, from an experiential data structure, metadata associated with the referenced user experience. For example, a query may include a place parameter for “restaurant” and a corresponding sub-type parameter for “seafood,” and a place parameter “Monterey.” In some examples, device 1300 may query one or more application framework components, such as a location framework, a routine framework, a map framework, and the like. For example, a location framework may store one or more locations visited by the user, such as a restaurant, theatre, or other business establishment. In some examples, the locations may be determined based on determining that the device location was detected at a specific location for a threshold amount of time. Using the parameters, for example, the location framework may be queried for metadata corresponding to a “seafood restaurant” in “Monterey” that also corresponds to the device location data.

In some examples, device 1300 retrieves, based on the metadata associated with the referenced user experience, one or more media items associated with the referenced user experience. For example, device 1300 may retrieve pictures, videos, music, or any other media items associated with the user experience corresponding to the seafood restaurant in Monterey. In some examples, a media application obtains media associated with a user profile, such as media generated by the user during the referenced user experience.

In some examples, media items may be obtained from a remote source, such as the Internet, when one or more predetermined criteria are satisfied. For example, if location data on the device determines that the user visited a seafood restaurant in Monterey, but the user did not generate any media while at the location, or only generated a small amount of media (e.g., one or two photos), then media items may be obtained from a third party source. For example, media items may be obtained from a business reviews application on device 1300. In some examples, other users may upload media items to a server associated with the business reviews application, and the media items uploaded by other users may be obtained based on the metadata. For example, the business reviews application may include media items from other users which are associated with the seafood restaurant in Monterey, and such media items are obtained based on the metadata.

In some examples, device 1300 outputs together the one or more media items associated with the referenced user experience. As shown in FIG. 13, for example, device 1300 outputs an interactive display of the one or more media items and information associated with the referenced user experience. In some examples, device 1300 generates, using the metadata, information associated with the referenced user experience and outputs the generated information together with the one or more media items. For example, in response to the user input “What was the seafood restaurant in Monterey,” device 1300 may utilize a maps application to generate map information based on location metadata associated with the restaurant in Monterey. Using location metadata, for example, the maps application may generate map information including the name of the location, specific location on the map, and surrounding area on the map. In another example, device 1300 may utilize a business reviews application to generate review information associated with the location. Using location metadata, for example, the business reviews application may generate information associated with the location, including but not limited to ratings, location type, cuisine types, price ranges, addresses, phone numbers, directions, e-mail addresses, website information, advertisements, user reviews, and the like. In some examples, the interactive display includes a summary portion 1304. For example, the summary portion 1304 may include a title of the referenced user experience, such as “Waterfront Restaurant,” and further may include address information and/or contact information. In some examples, the contact information includes a contact affordance 1310. For example, user activation of the contact affordance 1310 may initiate a telephone call to a business, home, or other contact associated with the referenced user experience, such as the “Waterfront Restaurant.” In some examples, the interactive display includes location information associated with the referenced user experience. For example, generated map information 1306 corresponding to the Waterfront Restaurant may be displayed. In some examples, the one or more media items may be output proximate to the information associated with the reference user experience. For example, one or more media items 1308 may be displayed below the generated map information 1306. In some examples, a user input, such as a gesture input, may cause the display to scroll upwards or downward to output additional media items and generated information associated with the referenced user experience (not depicted), such as business review information, calendar information, and the like.

FIG. 14 illustrates an electronic device 1400. In operation, device 1400 displays a user interface including at least one application, the at least one application associated with one or more parameters. In some examples, the at least one application may correspond to a contacts application, such as displayed contacts application 1402. The contacts application 1402 may include one or more contacts 1404, which may correspond to saved entries generated by the user or by device 1400. In some examples, the contacts 1404 are displayed in alphabetical order based on first or last name, for example. In some examples, the contacts application 1402 may be associated with one or more parameters. For example, each contact 1404 may be associated a “person” type parameter, such as a parameter for a name, nickname, or other identifier corresponding to a user.

In some examples, device 1400 determines whether the one or more parameters are associated with at least one user experience. In some examples, determining whether the one or more parameters are associated with at least one user experience includes determining whether the one or more parameters include at least one parameter type. In some examples, the parameter type may include a type for “event,” a type for “activity”, a type for “geographical feature, a type for “person,” and/or a type for “place.” In some examples, a type for “event” may be associated with a user experience for a trip, vacation, party, birthday, wedding, graduation, social event, or other events. In some examples, a type for “activity” may be associated with a user experience corresponding to running, skiing, camping, rafting, biking, hiking, riding, another workout, or other physical activities. In some examples, a type for “geographical feature” may be associated with a user experience corresponding to a beach, sand, mountains, a volcano, a lake, a river, an island, or any other geographical feature. In some examples, a type for “person” may be associated with a user experience in which another individual shared the same experience with the user. In some examples, the individual may be referred to by full name, nickname, or another reference to the individual. In some examples, a type for “place” may be associated with a user experience corresponding to a specific location or destination, such as a restaurant, hospital, hotel, bar, nightclub, golf club, park, or any other place. For example, device 1400 may determine that one or more contacts 1404 in the contacts application 1402 corresponds to a “person” type parameter, such as “John C. Smith.”

The one or more parameters referencing a user experience of a user may further include a sub-parameter type. In some examples, the sub-parameter type may include a sub-type corresponding to a type for “place,” such as the name of a store. For example, a parameter for a “place” type may include “grocery store,” and a parameter for the “place” sub-type may include “Nob Hill Foods.” As another example, a parameter for a “place” type may include “coffee shop,” and a parameter for the “place” sub-type may include “Starbucks.” As yet another example, a parameter for a “place” type may include “restaurant,” and a parameter for the “place” sub-type may include “Chinese” or “Italian.” The one or more parameters referencing a user experience of a user may further include a parameter descriptor type. In some examples, a parameter for an “activity” may include a “run,” and a parameter for the “activity” descriptor may include “long” or “short.” In some examples, a parameter for a “place” may include “store,” and a parameter for the “place” descriptor may include “busy” or “big.”

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1400 obtains, from an experiential data structure, metadata associated with the at least one user experience. The experiential data structure may be generated based on at least one pattern recognition process, for example. In some examples, the experiential data structure is generated, updated, and/or maintained by one or more pattern recognition components and/or one or more graph processing components. In some examples, at least one pattern recognition component and/or at least one graph processing component may periodically and/or continuously generate and update user experience metadata associated with the experiential data structure. For example, while the user is vacationing in Hawaii, the at least one pattern recognition component and/or at least one graph processing component periodically updates user experience metadata associated with a user experience for “trip” in “Hawaii.” For example, a user experience titled “Kauai” may be generated based on the user experience.

In some examples, device 1400 determines at least one pattern associated with the user. For example, information may be periodically or continuously collected from user interactions or other inputs received at the device, such as from applications and sensors associated with the device. Applications from which information is collected may include photo applications, video applications, instant messaging applications, e-mail applications, or any other applications associated with device 1400. In some examples, information collected from instant messaging application, e-mail application, or calendar application may indicate that one or more individuals shared the user experience with the user. For example, messages received during the time when the user visited Hawaii may indicate that another user joined the user on the trip. As another example, itinerary information obtained from e-mail messages may indicate that another user joined the user on the trip. As yet another example, calendar event information may indicate that another user accepted an invite for a trip. In some examples, device 1400 may obtain metadata identifying “John C. Smith” as a contact who shared one or more user experiences with the user. In some examples, another person's presence is detected based on another device's proximity to the user device during the user experience. For example, proximity of another device may be determined using Bluetooth or another wireless protocol, such as via an application for finding another person.

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1400 displays an affordance associated with the at least one application. For example, device 1400 may display one or more affordances 1406 a, 1406 b, and/or 1406 c associated with the contacts application. In some examples, the one or more affordances 1406 may be displayed proximate to, next to, or otherwise in connection with one or more contacts 1404. In some examples, affordances 1406 may be displayed proximate to contacts 1404 that correspond to one or more parameters associated with at least one user experience. For example, based on obtained metadata, “John C. Smith” may be determined to be associated with a user experience corresponding to a user trip to Hawaii.

In some examples, device 1400 receives a user input including a selection of the affordance associated with the at least one application. For example, the user may select the affordance based on a touch input (e.g., finger press). In some examples, in response to receiving the user input, the device 1400 outputs at least one media item based on the metadata associated with the at least one user experience. In some examples, prior to outputting at least one media item based on the metadata associated with the at least one user experience, device 1400 may output one or more links to a plurality of user experiences. As shown in FIG. 14, device 1400 may output links to a plurality of user experiences 1410, 1412, and/or 1414. In some examples, each user experience associated with links 1410, 1412, and/or 1414 correspond to user experiences with the contact “John C. Smith,” based on selection of affordance 1406-a. In some examples, activation of links 1410, 1412, and/or 1414 may cause output at least one media item based on the metadata associated with the at least one user experience corresponding to the activated link. For example, user selection of link 1410 titled “Kauai” may cause output of at least one media item corresponding to the user's trip to Hawaii with “John C. Smith.”

In some examples, links 1410, 1412, and/or 1414 are displayed within the contacts application 1402. In some examples, in response to receiving the user input, the device 1400 outputs together at least one media item based on the metadata associated with the at least one user experience and information associated with the at least one user experience. In some examples, activation of links 1410, 1412, and/or 1414 may cause output together of at least one media item based on the metadata associated with the at least one user experience corresponding to the activated link and information associated with the at least one user experience corresponding to the activated link. In some examples, activation of one or more affordances displayed next to contact 1408 may cause a telephone call, FaceTime session, instant messaging session, or other activity to be invoked.

FIG. 15A illustrates an electronic device 1500. In operation, device 1500 displays a user interface including at least one application, the at least one application associated with one or more parameters. In some examples, the at least one application may correspond to a maps application, such as displayed maps application 1502. The maps application 1502 may include representations of physical features, such as streets, highways, homes, business, parks, and the like. In some examples, the maps application 1502 may be associated with one or more parameters. For example, the one or more representations of physical features may be associated with one or more parameters, such as a parameter corresponding to a public place, such as “Dolores Park”, or a geographical feature, such as “Ocean Beach.” In some examples, the maps application 1502 may include an affordance for adjusting one or more time and date parameters. For example, maps application 1502 may include an affordance 1504 for adjusting a time range to display relevant affordances for user experiences based on the selected time. In some examples, a user may input one or more user gestures in order to change a time range of the affordance 1504. For example, the user may adjust the affordance using one or more user gestures to “zoom-in” and/or “zoom-out” in order to change the time range to/from hours, days, weeks, months, years, and the like.

In some examples, device 1500 determines whether the one or more parameters are associated with at least one user experience. In some examples, determining whether the one or more parameters are associated with at least one user experience includes determining whether the one or more parameters include at least one parameter type. For example, device 1500 may determine that the representation of “Dolores Park” within maps application 1502 corresponds to a “place” type parameter. In another example, device 1500 may determine that the representation of “Ocean Beach” corresponds to a “geographical feature” type parameter.

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1500 obtains, from an experiential data structure, metadata associated with the at least one user experience. The experiential data structure may be generated based on at least one pattern recognition process, for example. In some examples, the experiential data structure is generated, updated, and/or maintained by one or more pattern recognition components and/or one or more graph processing components. For example, while the user is engaged in activities throughout San Francisco, the at least one pattern recognition component and/or at least one graph processing component generates and updates user experience metadata associated with a user experience at “Dolores Park” and “Ocean Beach.” In some examples, the metadata includes location information, media information, contact information, time and date information, message and/or e-mail information, and the like. In some examples, a user selection of a specific time and/or date range based on affordance 1504 may provide metadata associated with time information.

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1500 displays an affordance associated with the at least one application. In some examples, device 1500 may display one or more affordances 1506 a, 1506 b, 1506 c, 1506 d, and 1506 e associated with the maps application. In some examples, the one or more affordances 1506 may be displayed proximate to, next to, or otherwise in connection with one or more representations of physical features. In some examples, affordances 1506 may be displayed proximate to representations of physical features that correspond to one or more parameters associated with at least one user experience. For example, based on obtained metadata, the parameter “Presidio” may be determined to be associated with a user experience corresponding to a user visit to The Presidio in San Francisco. In some examples, affordance 1506 a may correspond to the user experience for the user's visit to The Presidio. In another example, based on obtained metadata, the parameter “Golden Gate Park” may be determined to be associated with a user experience corresponding to a user visit to Golden Gate Park in San Francisco. In some examples, affordance 1506 b may correspond to the user experience for the user's visit to Golden Gate Park. In yet other examples, the size, color, and/or shape of the one or more affordances 1506 may be based on attributes associated with the user experience. For example, the size of an affordance may be based on a time period, such that longer experiences are associated with larger or smaller sizes. As another example, the size of an affordance may be based on a number of people that shared the experience with the user, such that more shared users are associated with larger or smaller sizes. As another example, the color of an affordance may be based on one or more event types, place types, activity types, geographical location types, and/or person types. In some examples, affordances 1506 may include one or more icons associated with a semantic meaning, such as a “face” icon associated with a person, a “building” icon associated with a place, a “bike” icon associated with an activity, a “mountain” icon associated with a geographical feature, a “food” icon associated with an event, and the like.

In some examples, device 1500 receives a user input including a selection of the affordance associated with the at least one application. For example, the user may select one of the affordances 1506 using on a touch input (e.g., finger press). In some examples, in response to receiving the user input, the device 1500 outputs at least one media item based on the metadata associated with the at least one user experience. In some examples, outputting at least one media item based on the metadata associated with the at least one user experience including displaying an overview 1508 of the user experience within the maps application with specific locations that the user visited during one or more user experience, as shown in FIG. 15B. For example, an overview 1508 of the user experience may be displayed within the maps application, such as by zooming in or out to a relevant location associated with the user experience. In some examples, the overview 1508 of the user experience includes a summary of the points of interest and events associated with the user experience. For example, the overview 1508 may include a starting point location 1510 of the user experience, a path 1512 that the user traveled during the user experience, and one or more locations 1514 visited during the user experience. As another example, the overview 1508 may include representations 1516 of messages received during the user experience. In some examples, overview 1508 may include an affordance 1518 for adjusting one or more time and date parameters. For example, affordance 1518 may permit a user to adjust a time and/or date range to display relevant overviews of user experiences based on the selected time and date. In some examples, a user may input one or more user gestures in order to change a time range of the affordance 1518. For example, the user may adjust the affordance using one or more user gestures to “zoom-in” and/or “zoom-out” in order to change the time range to/from hours, days, weeks, months, years, and the like.

In some examples, outputting at least one media item based on the metadata associated with the at least one user experience may further include a user selection of one or more displayed representations within overview 1508 to cause output of further media items and/or information associated with a user experience. For example, user selection of one or more locations 1514 visited during the user experience may further cause media items and/or information associated with the user experience to be displayed. For example, location 1514 a may correspond to a user visit to “Dolores Park,” where user selection of the location 1514 a causes pictures, video, and/or other information associated with a user experience at “Dolores Park” to be displayed. In some examples, text associated with the user experience corresponding to the affordances 1514 may be displayed. For example, the text “Breakfast at Tartine Bakery” corresponding to affordance 1514 b may be displayed. In some examples, the text may include timing information associated with the user experience, such as “9:35 am-10:45 am, Breakfast at Tartine Bakery.”

FIG. 16 illustrates an electronic device 1600. In operation, device 1600 displays a user interface including at least one application, the at least one application associated with one or more parameters. In some examples, the at least one application may correspond to a calendar application, such as displayed calendar application 1602. The calendar application 1602 may include one or more calendar events 1604 a, 1604 b, and 1604 c, which may each correspond to saved entries generated by the user or by device 1600. In some examples, the one or more calendar events 1604 are displayed in chronological order. For example, calendar events 1604 a, 1604 b, and 1604 c may correspond to events throughout a selected day in the calendar application 1602. In some examples, the contacts application 1602 may be associated with one or more parameters. For example, one or more calendar event 1604 may be associated an “event” type parameter, such as a parameter for a lunch, dinner, sporting event, class, workshop, business meeting, flight, and the like. In some examples, one or more calendar events 1604 may be associated a “person” type parameter, such as an event for a lunch or dinner with a specific contact. In some examples, one or more calendar events 1604 may be associated a “place” type parameter, such as an event for a lunch or dinner at a specific restaurant.

In some examples, device 1600 determines whether the one or more parameters are associated with at least one user experience. In some examples, determining whether the one or more parameters are associated with at least one user experience includes determining whether the one or more parameters include at least one parameter type. In some examples, device 1600 may determine that one or more calendar events 1604 in the contacts application 1402 corresponds to one or more parameters. For example, device 1600 may determine that calendar event 1604 b corresponds to an “event” type parameter associated with a “workshop,” and a “place” type parameter associated with “De Young Museum.”

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1600 obtains, from an experiential data structure, metadata associated with the at least one user experience. For example, device 1600 may obtain, from an experiential data structure, metadata associated with parameters corresponding to one or more calendar entries 1604. In some examples, obtaining metadata associated with the referenced user experience includes querying one or more applications associated with device 1600. For example, with respect to the calendar event 1604 b, a query may include an “event” type parameter associated with a “workshop,” and a “place” type parameter associated with “De Young Museum.” In some examples, the query is sent to applications including a notes application in order to obtain metadata associated with notes created by the user and corresponding to the referenced user experience. For example, the user may have invoked the notes application while at the De Young Museum, and created an entry in the notes application while at the museum. As another example, the query is sent to a media application in order to obtain metadata associated with photos or videos created by the user and corresponding to the user experience for the De Young Museum.

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1600 displays an affordance associated with the at least one application. For example, device 1600 may display one or more affordances, such as an affordance 1606, associated with the contacts application. In some examples, the one or more affordances 1606 may be displayed proximate to, next to, or otherwise in connection with one or more calendar entries 1604. In some examples, affordances 1606 may be displayed proximate to one or more calendar entries 1604 that correspond to one or more parameters associated with at least one user experience. For example, based on obtained metadata, calendar entry 1604 b may be determined to be associated with a user experience corresponding to a user visit to the De Young Museum, based on an “event” type parameter associated with a “workshop,” and a “place” type parameter associated with “De Young Museum.” In some examples, an affordance, such as affordance 1606, is displayed proximate to calendar entry 1604 b based on determining that the one or more parameters are associated with at least one user experience.

In some examples, device 1600 receives a user input including a selection of the affordance associated with the at least one application. In some examples, the user may select the affordance based on a touch input (e.g., finger press). For example, a user may select affordance 1606 associated with calendar entry 1604 b. In some examples, in response to receiving the user input, the device 1600 outputs at least one media item. In some examples, outputting at least one media item based on the metadata associated with the at least one user experience includes outputting information based on the metadata associated with the at least one user experience, such as summary information or other information. As shown in FIG. 16, device 1600 outputs summary information 1608 corresponding to the user experience, including, for example, an event title, event location, and time and/or date information. In some examples, device 1600 outputs one or more media items 1610 corresponding pictures and videos taken during the user's visit to the De Young Museum. In some examples, device 1600 outputs one or more media items corresponding to individual still pictures, short animated pictures, and/or videos taken during the user's visit to the De Young Museum. In some examples, device 1600 outputs information 1612 corresponding to the user experience, such as notes that were taken by the user while at the art museum. In some examples, the notes information 1612 may correspond to notes generates in a notes application on device 1600.

FIG. 17 illustrates an electronic device 1700. In operation, device 1700 displays a user interface including at least one application, the at least one application associated with one or more parameters. In some examples, the at least one application may correspond to a music application, such as displayed music application 1702. The music application 1702 may include one or more media items 1704, such as songs, which may correspond to songs downloaded, purchased, or otherwise obtained by the user, for example. In some examples, song 1704 are displayed in a specific order, such as alphabetical order, by album, by artist, and the like. In some examples, the music application 1704 may be associated with one or more parameters. For example, each song 1704 may be associated an “event” type parameter and/or a “place” type parameter.

In some examples, device 1700 determines whether the one or more parameters are associated with at least one user experience. In some examples, determining whether the one or more parameters are associated with at least one user experience includes determining whether the one or more parameters include at least one parameter type. In some examples, device 1700 may determine that one or more songs 1704 in the music application 1702 correspond to one or more parameters. For example, device 1700 may determine that song 1704 a corresponds to a “geographical” type parameter associated with a “beach,” and a “place” type parameter associated with “Half Moon Bay.” In some examples, the association between a song 1704 and the one or more parameters may be generated based on a user selection to play a song 1704 during one or more user experience. For example, during a recent trip to the location “Half Moon Bay,” the user may have selected song 1704 to be played while at “Half Moon Bay,” and thus, song 1704 is associated with a “place” type parameter for “Half Moon Bay.”

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1700 obtains, from an experiential data structure, metadata associated with the at least one user experience. For example, device 1700 may obtain, from an experiential data structure, metadata associated with parameters corresponding to one or more songs 1704. In some examples, obtaining metadata associated with the referenced user experience includes querying one or more applications associated with device 1700. For example, with respect to song 1704 a, a query may include an “place” type parameter associated with “Half Moon Bay,” and a “geographical feature” type parameter associated with “beach.” In some examples, the query is sent to a media application in order to obtain metadata associated with media created by the user and corresponding to the referenced user experience. For example, the user may have taken pictures or video while listening song 1704 a, and metadata corresponding to the pictures or video are obtained. In some examples, a query is sent to a calendar application in order to obtain metadata associated with one or more calendar entries generated by the user or device 1700, and corresponding to song 1704 a. For example, the user may have played the song 1704 a while at Half Moon Bay, another beach, or any other location. In some examples, metadata is obtained for times and/or dates corresponding to instances when song 1704 a was played.

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1700 displays an affordance associated with the at least one application. For example, device 1700 may display one or more affordances, such as affordances 1706, associated with the music application. In some examples, the one or more affordances 1706 may be displayed proximate to, next to, or otherwise in connection with one or more song 1704. In some examples, affordances 1706 may be displayed proximate to one or more songs 1704 that correspond to one or more parameters associated with at least one user experience. For example, based on obtained metadata, song 1704 a may be determined to be associated with a user experience corresponding to one or more beaches or other locations, such as Half Moon Bay. For example, the user may have played song 1704 a during the visit to the one or more beaches or other locations. In some examples, an affordance 1706 a is displayed proximate to song 1704 a based on determining that the one or more parameters are associated with at least one user experience.

In some examples, device 1700 receives a user input including a selection of the affordance associated with the at least one application. In some examples, the user may select the affordance based on a touch input (e.g., finger press). For example, a user may select affordance 1706 a associated with song 1704 a. In some examples, in response to receiving the user input, the device 1700 outputs at least one media item. As shown in FIG. 17, device 1700 outputs one or more media items 1708 corresponding pictures and videos taken during or proximate to a time when the user listened to song 1704 a. In some examples, the one or more media items 1708 include a summary slideshow of pictures and/or videos automatically generated from pictures and/or videos taken by the user during the user experience, with music corresponding to song 1704 a played as a background soundtrack during playback of the summary slideshow. In some examples, device 1700 outputs one or more media items corresponding to individual still pictures, short animated pictures, and/or videos taken during or proximate to a time when the user listened to song 1704 a.

In some examples, outputting at least one media item based on the metadata associated with the at least one user experience includes outputting information based on the metadata associated with the at least one user experience, such as summary information or other information. In some examples, device 1700 outputs information corresponding to the user experience, such as location information 1710 that corresponds to a location where the user played song 1704 a. For example, location information may be displayed using a maps view and containing location indicators for locations where the user played song 1704 a. In some examples, device 1700 outputs information such as calendar information 1712 that corresponds to a times and/or dates when the user played song 1704 a. For example, calendar information may be displayed using a calendar view and containing date indicator for dates when the user played song 1704 a.

FIG. 18A illustrates an electronic device 1800. In operation, device 1800 displays a user interface including at least one application, the at least one application associated with one or more parameters. In some examples, the at least one application may correspond to a messages application, such as displayed messages application 1802. The messages application 1802 may include one or more messages 1804 and/or 1806 of a conversation 1808. For example, messages 1804 may includes messages received at device 1804 from another user, and messages 1806 may include messages sent by the user of device 1800. In some examples, the messages may include media, such as photos or videos. For example, received message 1804 may include a photo. In some examples, the messages may include text, such as sent messages 1806. In some examples, the messages application 1802 may be associated with one or more parameters. For example, one or more messages 1804 and 1806 may be associated with a “person” type parameter, such as a parameter for a name, nickname, or other identifier corresponding to a user of the conversation 1808. As another example, one or more messages 1804 and 1806 may be associated an “event” type parameter, such as a parameter for an event referenced within the conversation 1808. As yet another example, one or more messages 1804 and 1806 may be associated a “place” type parameter, such as a parameter for a place referenced within the conversation 1808.

In some examples, device 1800 determines whether the one or more parameters are associated with at least one user experience. In some examples, determining whether the one or more parameters are associated with at least one user experience includes determining whether the one or more parameters include at least one parameter type. In some examples, device 1800 may determine that one or more messages 1806 in the messages application 1802 corresponds to one or more parameters. For example, device 1800 may determine that message 1806 a, which includes the text “John's wedding yesterday was awesome,” corresponds to an “event” type parameter associated with a “wedding,” and a “person” type parameter associated with “John.” As another example, device 1800 may determine that message 1806 b, which includes the text “We need to plan our trip to Hawaii this summer,” corresponds to a “place” type parameter associated with “Hawaii.”

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1800 obtains, from an experiential data structure, metadata associated with the at least one user experience. For example, device 1800 may obtain, from an experiential data structure, metadata associated with parameters corresponding to one or more messages 1804 or 1806. In some examples, obtaining metadata associated with the referenced user experience includes querying one or more applications associated with device 1800. For example, with respect to message 1806 a, a query may include an “event” type parameter associated with a “wedding,” and a “person” type parameter associated with “John.” In some examples, the query is sent to applications including a media application in order to obtain metadata associated with photos or videos created by the user and corresponding to the user experience for “John” and “wedding.”

In some examples, in response to determining that the one or more parameters are associated with at least one user experience, device 1800 displays an affordance associated with the at least one application. For example, device 1800 may display one or more affordances, such as affordance 1810, associated with the messages application 1802. In some examples, the one or more affordances 1810 may be displayed proximate to, next to, or otherwise in connection with one or more messages 1804 and 1806. In some examples, affordances 1810 may be displayed proximate to one or more messages that correspond to one or more parameters associated with at least one user experience. For example, based on obtained metadata, message 1806 a may be determined to be associated with a user experience corresponding to a user experience for John's wedding, based on an “event” type parameter associated with a “wedding,” and a “person” type parameter associated with “John.” In some examples, the one or more affordances 1810 may be represented by underlining associated text, such as by underlining the words “John's wedding,” where user activation of the affordance includes the user activating the underlined text.

In some examples, device 1800 receives a user input including a selection of the affordance associated with the at least one application. In some examples, the user may select the affordance based on a touch input (e.g., finger press). For example, a user may select affordance 1810 a associated with messages 1806 a. In some examples, in response to receiving the user input, the device 1800 outputs at least one media item. As shown in FIG. 18B, device 1800 outputs one or more media items 1812 corresponding to a summary slideshow of pictures and videos that the user captured during “John's Wedding.” In some examples, device 1800 outputs one or more media items 1814 corresponding to individual still pictures, short animated pictures, and/or videos that the user captured during “John's Wedding.” In some examples, in response to a user selection of the one or more media items, a user may send the one or more media items to another user. For example, the user may select one or more media items 1812 and 1814, and further select affordance 1816. In response to the user selections of media items and affordance 1816, device 1800 may display the messages application 1802 including the selected media items, as shown in FIG. 18C. For example, messages application 1802 may permit a user to send the selected media items 1818 to one or more contacts 1820.

FIG. 19 illustrates process 1900 for delivering content associated with a user experience, according to various examples. Process 1900 is performed, for example, using one or more electronic devices implementing a digital assistant. In some examples, process 1900 is performed using a client-server system (e.g., system 100), and the blocks of process 1900 are divided up in any manner between the server (e.g., DA server 106) and a client device. In other examples, the blocks of process 1900 are divided up between the server and multiple client devices (e.g., a mobile phone and a smart watch). Thus, while portions of process 1900 are described herein as being performed by particular devices of a client-server system, it will be appreciated that process 1900 is not so limited. In other examples, process 1900 is performed using only a client device (e.g., user device 104) or only multiple client devices. In process 1900, some blocks are, optionally, combined, the order of some blocks is, optionally, changed, and some blocks are, optionally, omitted. In some examples, additional steps may be performed in combination with the process 1900. By delivering content associated with a user experience as described herein, the user is conveniently reminded of media and generated during a referenced user experience, in addition to any information requested for the referenced user experience. Furthermore, additional information, such as the location of an experience, or music the user listened to during the experience, are woven into a response to provide a content-rich experience. Additionally, facilitating user interaction in this manner provides for a unique and improved user experience, and provides the user with greater awareness of the capabilities of the electronic device. These features also improve battery life of the device by reducing the need of a user to search through applications for desired information

At block 1905, the electronic devices receives, from a user, speech input.

At block 1910, the electronic device determines whether the speech input corresponds to a user intent of obtaining information associated with a user experience of the user. In some examples, determining whether the speech input corresponds to a user intent of obtaining information associated with a user experience includes determining whether the speech input corresponds to a user intent of obtaining media associated with the user experience. In some examples, determining whether the speech input corresponds to a user intent of obtaining information associated with a user experience includes determining whether the speech input includes one or more nouns related to images and one or more nouns related to an experience. In some examples, determining whether the speech input corresponds to a user intent of obtaining information associated with a user experience includes determining whether the speech input includes at least one semantic term for an experience, at least one verb for a past activity, and at least one verb for a search. By determining whether the speech input corresponds to a user intent of obtaining information associated with a user experience in this manner, the intent may be determined based on a variety of criteria, such as present of specific verbs (e.g., past activities), semantics for user experiences (e.g., “memories” or “highlights”), or search related phrases (e.g., “lookup,” “find,” etc.). For example, by recognizing that the user is searching for information from a past experience, or explicitly requesting experience related media, the claimed process improves intent determination for obtaining information associated with a user experience.

At block 1915, in response to a determination that the speech input corresponds to a user intent of obtaining information associated with a user experience of the user, the electronic device identifies, from the speech input, one or more parameters referencing a user experience of the user. In some examples, identifying, from the speech input, one or more parameters referencing a user experience includes determining whether the speech input includes at least one parameter type corresponding to an event, an activity, a geographical feature, a person, a place, a time, or a location. In some examples, identifying, from the speech input, one or more parameters referencing a user experience includes determining whether the speech input includes at least one parameter sub-type corresponding to at least one parameter type. In some examples, identifying, from the speech input, one or more parameters referencing a user experience includes determining whether the speech input includes at least one descriptor corresponding to at least one parameter type. By identifying one or more parameters referencing a user experience of the user in this manner, a relevant user experience may be determined based on key parameters referenced in the user input. That is, key parameters referenced in the user input, such as specific events, activities, geographical features, people, and places, serve as a trigger to fetch relevant user experiences corresponding to the speech input. For example, by recognizing that the user is searching for information for a specific activity or person, the claimed process improves user experience determination by focusing on the primary elements related to experiences.

At block 1920, the electronic device obtains, from an experiential data structure, metadata associated with the referenced user experience. In some examples, the experiential data structure is generated based on at least one pattern recognition process. In some examples, at least one pattern associated with the user is determined, and in accordance with a determination that the at least one pattern associated with the user satisfies one or more predetermined criteria, the experiential data structure is updated. In some examples, updating the experiential data structure includes determining whether a user experience associated with the at least one pattern was previously generated. In some examples, in accordance with a determination that a user experience associated with the at least one pattern was previously generated, the previously generated user experience is updated. In some examples, in accordance with a determination that a user experience associated with the at least one pattern was not previously generated, a user experience associated with the at least one pattern is generated. In some examples, the experiential data structure is generated based at least on user data obtained from a secondary device. In some examples, the experiential data structure is generated based at least on user motion data. In some examples, the experiential data structure is generated based at least on user biometric data. In some examples, the experiential data structure is generated based at least on facial recognition data. In some examples, the experiential data structure is generated based at least on user contact data. By obtaining metadata associated with a referenced user experience in this manner, the process improves upon conventional information and media retrieval by leveraging experiential data structures. For example, by using pattern recognition and graph processing to generate and update user experience data, metadata pertaining to the user experience can be clustered and sorted for ease of retrieval upon receiving requests related to the user experiences. By further leveraging information such as user motions, biometric information, and facial recognition data, the claimed process provides an improved process for delivering content for user experiences.

At block 1925, the electronic device retrieves, based on the metadata associated with the referenced user experience, one or more media items associated with the referenced user experience. In some examples, retrieving, based on the metadata associated with the referenced user experience, one or more media items associated with the referenced user experience includes retrieving media items associated with a user profile. In some examples, in accordance with a determination that a predetermined criteria is satisfied, media items related to the referenced user experience may be retrieved from a remote source. In some examples, the predetermined criteria includes that a number of retrieved media items associated with the referenced user experience is less than a predetermined threshold. By retrieving one or more media items associated with the referenced user experience in this manner, the process improves content delivery in situations where user generated media in sparse or non-existent with respect to a given user experience. For example, where a user visited an iconic location (e.g., the Eiffel Tower) but was unable to generate media while at the location, images of the iconic location will still be included in media items that are ultimately displayed for the referenced user experience (e.g., a trip to Paris). In this way, the claimed process provides improved content delivery by considering the availability of user-generated content, and thus enhancing the displayed content.

At block 1930, the electronic device outputs together the one or more media items associated with the referenced user experience. In some examples, outputting together the one or more media items associated with the referenced user experience includes generating, using the metadata, information associated with the referenced user experience, and outputting together the one or more media items associated with the referenced user experience and the generated information associated with the referenced user experience. By outputting the one or more media items associated with the referenced user experience together with the generated information associated with the referenced user experience, the electronic device provides an enhanced, content-rich experience in response to a user request for information associated with a user experience. For example, in response to a general request for information, such as the name of a restaurant the user recently visited, the user is reminded of photos and videos that the user captured while at the restaurant, in addition to the name of the restaurant. Furthermore, additional information, such as the names of other individuals who accompanied the user at the restaurant, or notes the user took on the device while at the restaurant, are seamlessly provided to the user in response to the request. Additionally, facilitating user interaction in this manner provides for a unique and improved user experience, and provides the user with greater awareness of the capabilities of the electronic device. In turn, these processes reduce power usage and improve battery life of the device by reducing the need of a user to search through multiple applications for information and/or media pertaining to a user experience.

The operations described above with reference to FIG. 19 are optionally implemented by components depicted in FIGS. 1-4, 6A-B, and 7A-C. For example, the operations of process 1900 may be implemented by one or more of operating system 718, applications module 724, I/O processing module 728, STT processing module 730, natural language processing module 732, vocabulary index 744, task flow processing module 736, service processing module 738, media service(s) 120-1, or processor(s) 220, 410, 704. It would be clear to a person having ordinary skill in the art how other processes are implemented based on the components depicted in FIGS. 1-4, 6A-B, and 7A-C.

FIG. 20 illustrates process 2000 for delivering content associated with a user experience, according to various examples. Process 2000 is performed, for example, using one or more electronic devices implementing a digital assistant. In some examples, process 2000 is performed using a client-server system (e.g., system 100), and the blocks of process 2000 are divided up in any manner between the server (e.g., DA server 106) and a client device. In other examples, the blocks of process 2000 are divided up between the server and multiple client devices (e.g., a mobile phone and a smart watch). Thus, while portions of process 2000 are described herein as being performed by particular devices of a client-server system, it will be appreciated that process 2000 is not so limited. In other examples, process 2000 is performed using only a client device (e.g., user device 104) or only multiple client devices. In process 2000, some blocks are, optionally, combined, the order of some blocks is, optionally, changed, and some blocks are, optionally, omitted. In some examples, additional steps may be performed in combination with the process 2000. By delivering content associated with a user experience as described herein, the electronic device provides enhanced user interaction while a user is engaged with a respective application. For example, while searching a map for a restaurant, the user may be reminded of media that was generated while the user was at sporting event nearby. In turn, the user may recall an enjoyable experience at the sporting event, and recommend the sporting event to another user. Furthermore, additional information, such as calendar event data or notes related to the sporting event, are provided to the user. These processes provide for an enriched user experience by providing an option to view media and other content associated with relevant displayed information, while minimizing intrusion of the user's interaction with an application.

At block 2005, the electronic device displays a user interface including at least one application, the at least one application associated with one or more parameters.

At block 2010, the electronic device determines whether the one or more parameters are associated with at least one user experience. In some examples, determining whether the one or more parameters are associated with at least one user experience includes determining whether the one or more parameters are associated with at least one parameter type corresponding to an event, an activity, a geographical feature, a person, a place, a time, or a location. In some examples, determining whether the one or more parameters are associated with at least one user experience includes determining whether the one or more parameters are associated with at least one parameter sub-type corresponding to at least one parameter type. In some examples, determining whether the one or more parameters are associated with at least one user experience includes determining whether the one or more parameters are associated with at least one descriptor corresponding to at least one parameter type. In some examples, determining whether the one or more parameters are associated with at least one user experience includes determining displayed content corresponding to the application, and further determining whether the one or more parameters are associated with displayed content corresponding to the application. By identifying one or more parameters referencing a user experience in this manner, a relevant user experience may be determined based on parameters related to content in a displayed application. That is, key parameters related to displayed content, such as specific events, activities, geographical features, people, and places, serve as a trigger to fetch relevant user experiences corresponding to displayed content. For example, by recognizing that the user is searching through a contacts application, the claimed process improves user experience determination by focusing on experiences related to the displayed contacts.

At block 2015, in response to determining that the one or more parameters are associated with at least one user experience, the electronic device obtains, from an experiential data structure, metadata associated with the at least one user experience. In some examples, the experiential data structure is generated based on at least one pattern recognition process. In some examples, at least one pattern associated with the user is determined. In some examples, in accordance with a determination that the at least one pattern associated with the user satisfies one or more predetermined criteria, the experiential data structure is updated. In some examples, updating the experiential data structure includes determining whether a user experience associated with the at least one pattern was previously generated. In some examples, in accordance with a determination that a user experience associated with the at least one pattern was previously generated, the previously generated user experience is updated. In some examples, in accordance with a determination that a user experience associated with the at least one pattern was not previously generated, a user experience associated with the at least one pattern is generated. In some examples, the experiential data structure is generated based at least on user data obtained from a secondary device. In some examples, the experiential data structure is generated based at least on user motion data. In some examples, the experiential data structure is generated based at least on user biometric data. In some examples, the experiential data structure is generated based at least on facial recognition data. In some examples, the experiential data structure is generated based at least on user contact data. By obtaining metadata associated with a referenced user experience in this manner, the process improves upon conventional information and media retrieval by leveraging experiential data structures. For example, by using pattern recognition and graph processing to generate and update user experience data, metadata pertaining to the user experience can be clustered and sorted for ease of retrieval when a user is engaged with an application related to user experience metadata. By further leveraging information such as user motions, biometric information, and facial recognition data, the claimed process provides an improved process for delivering content for user experiences.

At block 2020, the electronic device displays an affordance associated with the at least one application. In some examples, the affordance associated with the at least one application is displayed in response to determining that the one or more parameters are associated with at least one user experience. By displaying an affordance associated with an application in this manner, the process improves user interaction with the device by providing the user with the option retrieve user experience content without being overly intrusive to the user's interaction with the application. Furthermore, by displaying the affordance in this manner, the claimed process informs the user of additional capabilities of the electronic device, such as user experience content retrieval.

At block 2025, the electronic device receives a user input including a selection of the affordance associated with the at least one application. In some examples, in response to receiving the user input receiving a user input including a selection of the affordance associated with the at least one application, the electronic device retrieves at least one media item related to the at least one user experience. In some examples, in accordance with a determination that a predetermined criteria is satisfied, the at least one media item related to the at least one user experience is retrieved from a remote source. In some examples, the predetermined criteria includes that a number of retrieved media items associated with the at least one user experience is less than a predetermined threshold. By retrieving one or more media items associated with the referenced user experience in this manner, the process improves content delivery in situations where user generated media in sparse or non-existent with respect to a given user experience. For example, where a user visited an iconic location (e.g., the Colosseum) but was unable to generate media while at the location, images of the iconic location will still be included in media items that are ultimately displayed for the referenced user experience (e.g., a trip to Rome). In this way, the claimed process provides improved content delivery by considering the availability of user-generated content, and thus enhancing the displayed content.

At block 2030, the electronic device outputs, in response to receiving the user input, at least one media item based on the metadata associated with the at least one user experience. In some examples, outputting at least one media item based on the metadata associated with the at least one user experience includes obtaining at least one media item associated with a user profile. By displaying an affordance associated with an application to cause output of media items upon selection, the electronic device provides an enhanced user experience while a user is engaged with a respective application. For example, while searching a map for a business meeting, the user may be reminded of photos and videos that the user captured while at a nearby restaurant. In turn, the user may recall the high quality of the restaurant, and subsequently suggest the restaurant for a client dinner. Furthermore, additional information, such as the names of other individuals who accompanied the user at the restaurant, or notes the user took on the device while at the restaurant, are seamlessly provided to the user while browsing the maps application. Additionally, facilitating user interaction in this manner provides for a unique and improved user experience, and provides the user with greater awareness of the capabilities of the electronic device. In turn, these processes reduce power usage and improve battery life of the device by reducing the need of a user to search through multiple applications for information and/or media pertaining to a user experience.

In accordance with some implementations, a computer-readable storage medium (e.g., a non-transitory computer readable storage medium) is provided, the computer-readable storage medium storing one or more programs for execution by one or more processors of an electronic device, the one or more programs including instructions for performing any of the methods or processes described herein.

In accordance with some implementations, an electronic device (e.g., a portable electronic device) is provided that comprises means for performing any of the methods or processes described herein.

In accordance with some implementations, an electronic device (e.g., a portable electronic device) is provided that comprises a processing unit configured to perform any of the methods or processes described herein.

In accordance with some implementations, an electronic device (e.g., a portable electronic device) is provided that comprises one or more processors and memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for performing any of the methods or processes described herein.

The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the techniques and their practical applications. Others skilled in the art are thereby enabled to best utilize the techniques and various embodiments with various modifications as are suited to the particular use contemplated.

Although the disclosure and examples have been fully described with reference to the accompanying drawings, it is to be noted that various changes and modifications will become apparent to those skilled in the art. Such changes and modifications are to be understood as being included within the scope of the disclosure and examples as defined by the claims.

As described above, one aspect of the present technology is the gathering and use of data available from various sources to improve the delivery to users of content that may be of interest to them. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, twitter IDs, home addresses, data or records relating to a user's health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information.

The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to deliver targeted content that is of greater interest to the user. Accordingly, use of such personal information data enables calculated control of the delivered content. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user's general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals.

The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country.

Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of delivering content for user experiences, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In another example, users can select not to provide location data for delivery of content for user experiences. In yet another example, users can select to limit the use of personal messages, such as instant messages or e-mail, for delivery of content for user experiences. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app.

Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user's privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods.

Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the content delivery services, or publicly available information.
